Well, I'll give this thread a whirl..
On the PC side:
Scorched 3D May be old news to some, but I just found it and it's kind of cool, if you find a few people on the net playing.
Also FullTiltPoker.Net Trying to decide if I'm good enough to put real money in it.
On the Amiga, I finished Heart of the Dragon. Back in the day the premise of the game engine seemed really cool (a time element) but the floppy loads were just brutal. Now with WHDload the loading problem is fixed, but that time element thing turned out to be a hassle. In the end I got pretty tired of it, and checked some spoilers to finish it quickly.
Also dug out Nuclear War. Aged pretty well, that game is still a lot of fun.
Also, from some chatting on irc I thought I'd give some Lemmings a try. New World Lemmings seems to suck bad, unless I've missed something. And Lemmings 2 was about how I remember... I played about 7-8 levels, hit a tough one and meh. I'm done. It's cute and all, but I'm done.
