De-Animator Fun flash game, if simplistic. It's pretty addictive though nowhere as addictive as Nanaca Crash. Zombie shooting is always a good pasttime though.
Uplink A very fun Hacking Simulation. Sure, it's not very realistic, but that's not the point. A get giddy and start smiling when I think about cracking open a bank in the game.
King of Dragon Pass Morgan on IRC was telling me about this. Looks pretty neat, like a Fantasy version of
Hidden Agenda. I'm checking out their demo version thing right now.
Strange Adventures in Infinite Space A fun quick game with a great sense of humor. I played the demo of it a while back and must say that it rocks. I think I'm going to have to buy it some day.
Spheres of Chaos An awesome psychadelic Asteroids clone/upgrade. The shareware version is a lot of fun, but since I played it nonstop for a couple days a long time ago I haven't felt the urge to get into it again. Worth playing for a while at least just so you can see and hear it. It's quite an amazing audiovisual treat.
Nanaca Crash Yes, I know, anyone reading this has probably played it already, but I'm including it just because it is so awesome.
Except for King of Dragon Pass, I can vouch that every game here is a fun one and worth checking out.
I'm finally going to get around to my Sid Meier's Pirates! review soon too.
