Most all the games (besides I think Bullet candy) have demos. The only one I personally played (demo) is Altitude and I really liked it after playing the demo online for like an hour. I was waiting for it to go on sale for a few weeks now, I bought it, but the only other ones I am interested in is Bullet Candy and Galcon Fusion, the others just aren't for me. I'll be trying the demos tomorrow probably, playing some Sup Com 2 (and being disappointed in skirmish mode currently)
