i thought i'd be funny to own a complete collection of ps2 2d games despite this hooplah about SCEA's stance on 2-D games. I just need a complete list here's what i've found so far:

Capcom vs. SNK 2: Mark of the Millennium
Culdcept
Guilty Gear
Guilty Gear XX
The King of Fighters 2000/2001
Street Fighter EX3
Super Bust-A-Move
Super Bust-A-Move 2
Marvel vs. Capcom 2
