just found a little gem of a game called Choice of Robots - it's basically an entirely text-based (no graphics or sound effects) Choose Your Own Adventure / Interactive Novel that has you be the creator of the first sentient robots etc., with lots of choice on how to design them and what to do with them (fittingly, I've only just gotten around to finally watching Battlestar Galactica ) There are lots of paths to take (seventy odd achievements, got 6 on my first playthrough), and wildly diverging ones as well. It's on Steam for a mere {insert the appropriate, but almost definitely single digit number of your local currency here}, much recommended if you like that kind of game!
