Just 5? Ugh
1. Final Fantasy X (No competition here)
2. Kingdom Hearts
3. Devil May Cry(1&2 both kicked ass)
4. Arc the Lad:TotS
5. Metal Gear Solid 2(Original and substance)
There are tons more I love also, Tekken Tag, Mark Of Kri(if you havnt played this your missing out), XenoSaga... i could go on
And shame on all of you for not picking FFX by far the best looking/playing/fun/entertaining game on the system!
