Let's just say that I'm an 'elderly' gamer. At this point everything is boring because I've seen it all before.
The only games that interest me are Paradox Grand Strategy games and this.
So definitely play this.
And Worms Armageddon. That's maybe older than you and the most fun game of chess you can ever have playing Kaos on the server.
But this is the best game for single player.

If you've never played Dwarf Fortress before - buy it. It is a great game unparalleled in it's genre, and Steam version has made it accessible to larger groups of gaming population by introducing mouse controls and overhauling UI.

If you've played and enjoyed DF "classic" then you will be disappointed by how big a setback Steam version is. Mouse control is the only advantage it offers over v. 0.47

First of all, Steam version is veeeery slow and time consuming due to following reasons;
- Cannot select an attack target from the list. You have to find it on the map!
- Cannot use keyboard to give job orders via manager. There is a hotkey for orders menu but no hotkey for "give a new order" and while you can write an AHK macros to mimic a new order hotkey you still have to use your mouse to click the order after typing it.
- Cannot use keyboard to draw stockpiles. There is "stockpiles" hotkey but no "make a new stockpie" hotkey. You have to use your mouse, or write an AHK macros.

Next, forget about all the great mods and tilesets we had for v 0.47. They are just incompatible. There are some decent mods, including graphics mods on Steam Workshop but it will take years until variety and customization gets anywhere close to that of v 0.47

Also we cannot check biomes boundaries anymore on the embark site screen.
Also the ice tiles turn invisible when the water freezes. They look like an unexplored section of the stone (they still look like they should if you switch to ASCII mode)

And i've been only playing for 23 hours.

I haven't played this game since 2012, back when you still had to install tilesets if you didn't want your game to appear as ASCII characters. I remember hearing about the "official" release back when the Steam version came out in 2022, but hadn't gotten around to playing it. Until now. I sank 50+ hours in over just a few days. I forgot how fun losing could truly be.
