well for my 5 would be: 1.Lumines , its just the fun addicting game you keep coming back to 2.NBA STREET oh sweet game man too too fun arcade style game fun franatic and fast paced 3. Resident evil 4 .long intense immersive and damn fun 4. Shadow of the colossus, ie is on the short side, but have you seen this game, have you played it!!!! 5. and of course Tony Hawk Pro Skater 4, before those underground days you'd keep coming back over and over again,maybe not better than part 3 but was superb. different genres should keep you going
