Enter the Matrix is crap, don't bother

best PS2 games? IMO:
God of War
Rachet and Clank: Up Your Arsenal!
Area-51 (FPS)
GTA: Double Pack (GTA III and GTA: VC)
GTA: San Andreas
Shadow of Rome
007: Everything Or Nothing
XMen Legends I and II
Mercenaries: Playground of Destruction
MGS III: Snake Eater
Syphon Filter: The Omega Strain
Okami (brilliant)
Tekken 4
Splinter Cell : Pandora Tomorrow (SC: DA on PS2 is awful, it's the most ripped version of the game on all platforms)
Legend of Kay
Project: Snowblind (FPS)
Half Life
Midnight Club II and Midnight Club III: DUB Edition
WWE SmackDown! Here Comes The Pain
Resident Evil 4
Siren
ofcourse i am missing many great ps2 games here, but most of these games are the best ps2 can offer (RE, GoW etc) list is long but worth it
