Ferocious, you completely ignore Sega games (Panzer Dragoon, Jet Set Radio Future, Gun Valkyrie, etc), Original Games that won't be ported anywhere (Project Gothem, DOA 3, etc.) and games that are ported, but improved (Silent Hill 2, Tony Hawk 2x, Genma Onimusha, maybe Tony Hawk will be improved as well. Who knows). Your comments about computer ports make no sense either. GTA 3 which is considered the best game on PS2 is coming to the PC for cheaper than the PS2 version. FFXI is coming to PC as well.
Forgot to list my current systems (meaning nothing older than Dreamcast to save some space):
Japanese Dreamcast (1998 launch console)
American Dreamcast (2001 cheap $45 console )
Xbox
Game Cube
PS2
Game Boy Advanced
Athlon XP 1600
Out of all of those, Dreamcast still gets the most play time. Rez and Shenmue II. Soon Sakura Taisen 4. Next would be Xbox since I want to perfect PGR (I still have 2 cars left). Game Boy Advanced with Golden Sun, Advanced Wars, Minna de Puyo Puyo and Breath of Fire. Then is Game Cube (Super Monkey Ball and Smash Brother whenever my friends come over). I'm waiting on Virtual Fighter 4 which is the sole reason I bought a PS2.
