Hear me out:

Monsters, Inc. Scream Team.

For a PS1 game it was ahead of its time. Fleshed out 3D levels that are actually navigable, decent camera angles, solid platforming + puzzles, and level revisiting that does not feel excessively repetitive. The difficulty is also not a god-awful sudden cliff like some PS1/2 games of the era. It’s one of the few, maybe the only PS1 game I’ve played multiple times through.

As a plus the soundtrack is banger.
