I am a 30+ year developer that decided to finally try game development. I'm currently working through the tutorials and find they are full of good information on unity and its tools. I can recommend GTGD S1 for anyone that already has a good understanding of programing and just looking to pick up unity development.
The author is obviously self-taught and talented but, that said, there are glaring mistakes in code that could be confusing to a novice programmer. His copy and pasting of code instead of creating a function, his misunderstanding of how some construct work and a general lack of OOP can be a bit of a distraction or teach bad habits to a novice developer.
I suggest anyone new to software development to find tutorials on C# that focus on “Object Oriented” programming first. Once you have an understanding of the basics these tutorials become more of a “What Can Unity Do” tutorial then a programming tutorial.
Even with the issues with the coding, I will recommend this as a good way to learn the basics of unity. The fact that this is based on Unity v3.4 is not that big a deal. The information should migrate to the next version with only a minimal effort; migrating code normal in software development and just another lesson.

There are a ton of misinformed fools leaving bad reviews on this video.

Unity is free to use, the tutorials are well paced out and informative. This is a great starting point for anyone interested in making a game.

GTGD is the akronym of "gamer to game developer".
It's a tutorial series which teaches the basics of developing a game in the Unity 3D engine (you can do 2D games as well, don't worry) by creating a simple multiplayer shooter.
It also includes some awesome feature programming like placing blocks.


This tutorial series has a very high production value. Both the sound and the resolution of the videos are very good and all the project files and scripts for the finished project are included in the download.

The tutor does a good job of explaining all the steps and tasks, not to slow or to fast and with a good amount of detail. Most importantly he does not skip anything, so you won't feel left alone.

A big part of this tutorial is coding. Make no mistake there is no way around that if you want to make your own games.

That said, even if you are a complete beginner at coding you should be able to follow the tutorial, though I would encourage you to at least read up on some basics (What is a class? What is a function? What is a variable?).
You will need them sooner or later anyway no matter what engine or programming language you use.

If you are intermediate the scripting won't bore you either. From a software development standpoint the scripts are very well structured, both in the way they interact and in and of themselves.
The scripts are kept simple and make no mistake, that is a big endorsement.
(If you don't know what I mean google the KISS principle.)
Still the tutor does not miss out on important elements of Unity coding and I was very happy to see some co-routine programming included where appropriate.
The tutor does an awesome job of commenting everything he writes and explaining what everything does, which makes it very easy to follow his train of thought.


If you are an aspiring gamedeveloper, beginner or intermediate, this tutorial series is well worth your money.
You do not need to buy any other software since both the game engine Unity 3D and the script editor MonoDevelop are free.
Yes, Unity has a commercial "Unity Pro" version but you don't need to worry about that at this point. The extra features included there are very specific and well beyond what you need to make most games, not to speak of just getting started in game development.
So all you need besides this tutorial is patience and time.
Learning takes effort and anyone who tells you otherwise is a charlatan and a liar.

But while there is no fast way to become a cometent developer, as far as learning effectiveness, pacing of content and completeness are concerned this is the best you will find.

So good luck and many squeals of delight ;).

THIS IS WHERE IT ALL STARTS!
If you want to start making games in Unity with no prior knowledge this is where you should start.
Not only does GTGD S1 teach the basics of unity but it also teaches you a way to order your games when building them.
(eg. enabling multiplayer then applying damage to enemy players).
The game you end up with at the end is pretty good (depending on how you change it). You might even get to play with friends and have fun with it (I know I did).

Please note GTGD is a series of videos and unity project files and Unity scripts. It's not a game creation tool like RPGmaker or GameMaker.

At my pace it took me about a month to make (there's about 30 videos and I was doing about 1 a day).

But one thing this game gave me is memories.
I will never forget the pain I suffered when trying to hide the mouse cursor through scripting and the ♥♥♥♥♥♥♥ amazing feeling I had when it finally worked.

And most of all I will never forget fighting back the tears as I finally got my friends to play this game. One thought went through my head that day. "They're playing a game I made!" "They're playing my game!" "They played MY game!" "They downloaded my game".

Or maybe that's just me.

Remember

You are more than a gamer.

I have 1 year of formal C# instruction under my belt, and about 5 hours of Unity and GIMP experience combined (mostly just navigating the windows and learning the controls). I've made a few 1-2 (imported) texture landscapes without any objects or anything. I have a good grasp on what each of the different softwares used in this tutorials series does, but very little experience actually using them first-hand (besides c# programming).

I'm on video 4 of the series (So take my review with a grain of salt, I may update after I finish the series) and I've just completed creating a projectile object which can be fired from the user as if it were a bullet of some kind. The video is very easy to follow, even using a never version of Unity (not reccommended).

I would warn buyers that the video series does not aim to teach you how to code in c# or how to use the different technologies showcased. It's more about following along, monkey-see-monkey-do style so you can see what goes on behind the scenes in game making. You will still need to learn more on your own to understand how everything works (especially the code).

For people who have never coded, or used any sort of game development technology, this will be hard to understand - easy to follow. By that I mean. You won't learn a ton about how the C# language works, you might not understand how Unity keeps track of all the objects or how it applies materials, and you might not become a GIMP artist, but you will be opened to a wonderful world of possibilities.

I highly suggest anyone without any programming or gamedevelopment experience consider buying this series and following every spoken word to the letter (most important when coding so you can keep track of the variables he's referring to). If you are a parent of gamer children, this would be a good series to get them into so they can get an idea of how games are made.

For those with programming experience, you will get the most out of this series if you take a look at the documentation to expand on

this is truly amazing. if you've ever been interested in developing games, you need to give this a shot. its also available FOR FREE on his website - gamertogamedeveloper.com

After FINALLY having the time to look into this. I finally started the series! I began watching the first 2 and so far I haven't been lost yet. Very professional. Very straight-forward. Very quick to the point without leaving you in the dust.

However, I'm a little disappointed on the price... When I first purchased this. I bought it within a few days it was released and the price originally was about $25. Now I see the price has been dropped to only a couple of bucks which is a little bit of a bummer to me :/

=EDIT=
This software is about to undergo a massive overhaul. Buying it at the moment will give you a once-useful tutorial that, while informative, applies to Unity 4 and contains outdated/incompatible information. You may not get much use out of this at the moment, but GTGD is currently reworking this with a remade season based on a modern version of Unity 5. Hang in there!
==

If you want the videos themselves for free, they're on the youtube channel GTGD.

Why would you buy it on Steam? For starters, it's an offline and downloadable version of the season with project files included, but usefulness may vary there. Why did I buy it? Well, why do you leave a tip for your waiter? It's a great series and it's easily understandable, plus it's designed using the free edition of Unity 4 for maximum accessibility-- a quality tutorial made entirely to assist others. It's absolutely commendable.

I'd recommend this to anyone who wants to learn the Unity engine. Why Unity? It's actually a great engine, and you shouldn't associate it with Air Control or any of that nonsense because if you look closely, you can see just how little effort was put into those shovelware titles. Countless exceptional titles have been made on the engine, ranging from Virtual Reality based shooters (H3VR, BAM) to visually stunning platformers (Ori, ReCore). The technology behind this engine is highly capable, despite a rather user-friendly interface, and great things can be accomplished with the engine if you set your mind to it.

While I'd say you should watch these videos on YouTube and decide for yourself whether you actually need the Steam version, GTGD certainly deserves every donation made from this.

These videos teach you Unity's interface, basic knowledge of C#, and more; arguably, they're more helpful than the actual Unity Technologies tutorial series.

If you truly wanted to know why this is on Steam, have a quote from the series creator himself...

Origineel geplaatst door GTGD:

It's important to study as many tutorials as time permits if you're into game development. You'll notice though that the overwhelming majority of tutorial creators can't continue regardless of how awesome their tutorials are. By having GTGD S1 on Steam I can fund the future of the series. There's a lot of expense and an incredible amount of time (years in the case of GTGD S1) that goes into making quality tutorials and a lot of people just don't realise that until they also start making tutorials. Relying on self advertising or setting up my own streaming website is a no go and isn't sustainable. Steam is the ideal place for getting game development in front of as many gamers as possible. It was Greenlit after all.

The developer just announced that he will remake the project in Unity 2017.
https://youtu.be/PL-iMEOfAVE
If you learned anything from the guy, if you followed any of his tutorials on his YT channel (because all of them are free there), and if you can afford to buy, do it, support him.
The fact that he decided to remake the series because it was obsolete and not leave it as it is, as the rest of the devs and not make a new one for the quick buck, proves the fact that he's a cool guy and he doesn't care just for the money.
I followed his tutorials for free on his YT channel when I couldn't afford buying them, but now that I can, I'll buy anything that puts out there, because he put more work into these projects and taught me, that any price he would put on these seems small.
Great job, man.
Thank you for these tutorials and looking forward to the new GTGD Series 1.

I originally said this sucked but it was my fault that it wasn't working. And the dev of game to game developer told me how to fix it! I definatly recomend this to anybody who has a dream of making easy games by themselves.
