Good advice. My buying and completion of Yakuza 1&2 (and Shadow of Colossus) are "to-do's" before getting the PS3.
Another "what game should I buy": Old Game Boy and Game Boy Color games, what should I buy? I got a GBA some months back and got all the good SEGA releases and now want to give the old Game Boy game support a try. Any ideas?
Mario Bros DX, Super Mario Land, Tetris, Legend of Zelda: Oracle of Seasons, Metroid 2, Battletoads in Ragnarok World, Pokemon Gold, Mr. Nuts, Arkanoid, Dropzone, Crystal Quest, Amazing Spiderman, Crazy Castle, Lion King, Pokemon Pinball, Yars' Revenge, Tarzan, Tom and Jerry, Metal Gear Solid, Pole Position, MotoCross Maniacs
Off the top of my head these are the ones I can think about with which I had most fun..
