(this little bit im adding is in fear of what could happen to my #1 favorite game of all tiime, Take2 has purchased this game and i hope the squad guys can keep them from burning mods. Most of the major updates and dlc for this game came from working closely with the modding community, should that vanish...... well lets just say i have a few backup copies of 1.2.2 and 1.3.3 just in case. Also the "making history" update is coming round because of mods, keep that in mind Take2, if you want to charge us money for that you'd damn sure better pay it out to the amazing modding community and not some measly $20 here or there im talking % of profit on some form of rolling time scale. Any way still my favorite game, still hard as hell, i just started playing it on Real Solar System, with realism overhaul because FML lol, and i still stand by my original review below)

This is my first review, so I chose to review the game with the most time spent in it. One day a friend mentions KSP on steam, tells me you build rockets and try to go to space. Said that would be fun and he tells me its very hard. I achieved orbit on my 5th rocket. He was not happy with me. Within 1 week i logged almost 130 hours. My friends had hosted an intervention to stop me from playing. Now im nearing 300 hours.....heh heh "logged" hours.

In all seriousness though this game is not for those who cannot be patient and be able to see the faults in thier own creation. This game is however for anyone looking to scratch that inner scientist, engineer, pilot in our head and put them each to work. There are tons of mods and plenty of people willing to help in the forums. If your not sure how to mod then I recommend looking up CKAN for Kerbal Space Program, It pretty much installs and updates, and everything else for you when it comes to mods.

I recommend this game to anyone that wants a real challenge and limitless sandbox solar system to play in.

1000 HR UPDATE!
Game is still strong, I am patiently waiting for KSP2.
The long term support this game has had by both the company and the community is amazin.
Even with the new one on the way I can't recommend this game enough.
If you have been on the fence then wait for a possible (if they ever again) put the game on sale and pick it up. OR when the inevitably bundle it with KSP2 I'd say get it then.

If you're really just not sure then don't buy this one. I'll update on how much I love or hate KSP2 and recommend it or this accordingly.
