Picked up Chaos Field (GC) and Omega Boost (PS1) this evening.
Yesterday I also picked up Double Dragon II (NES), Final Fight Guy (obviously), and then SSX Tour, Ninja Gaiden, Pariah, Knights of the Old Republic, PGR 2, & Prince of Persia: Sands of Time for the XBOX.
While I'm super excited about finding that copy of Final Fight Guy, I'm admittedly more excited about having a reason to bust out the old XBOX and giving it some love. I think now is about the best time to pick up the great XBOX games on the cheap. The 6 games I listed cost me about $25.00 at a local store. SSX, PGR 2 and Sands of Time were literally $3/game (complete and in very good condition). KOTOR was $10 and Ninja Gaiden was $6 (also complete and in very good condition). I used to hate on the original XBOX quite a bit, but there are plenty of solid games on the system and they're inexpensive. A lot of the multi platform releases are also cheaper on the system than on the PS2 or GC right now.
