I remember my teens by spending about an hour per day on Evolution: The World of Sacred Device. After playing a while I remembered why I loved it.... and hated it.
Still playing Skies of Arcadia(actually just now got the first moon gem)but now it is splitting time with Headhunter. I got a nice deal of $15 complete and shipped on it. It's a great game but the controls are a little off especially on the motorcycle.
God of War (finally) Thief 2 (Getting back into this one after a long hiatus. Awesome game; don't know why I stopped at the halfway point.) Serious Sam (Have to take frequent breaks from this one. It really wears me out.)
