Ive just never been a fan of adding features that arent needed. I like refining things that are there or adding things people actually wanted, like the movable camera in subsistence.
Anyways, here my top 5 favorite ps2 games in no particular order:
Mgs2
xenosaga 3
resident evil 4
devil may cry 3
shadow hearts covenant
Ahhh, back when japanese game creators had creativity running through their veins.........
Honorable mention to ffx, ffx-2, kh2, and odin sphere.
