Platformer is a game where it revolves around jumping from platform to platform. Uncharted has locations where its clearly a platformer, but its so much more, so i wouldn't call it a platformer.
The old Ratchet and Clanks where definitely platformers, but today it feels more like a shooter than a platformer. Is Contra a platformer? No it is a shooter, yet it has some jumps, so thats why Ratchet and Clank aren't platformers anymore. The first Jak and Daxter is definitely a platformer, the other 2 are platformers, but they are also open world games and shooters. Is Crackdown a platformer?
Ico is a puzzle game, it has some platforming to i know, but so does Zelda. Shadow of the Colossus is definitely not a platformer. LBP is a platformer, but if you take out the level customization it really isn't a good game, so its not the platforming that makes it great but rather the rest.
Sony platformers: Crash, Some Ratchets not all and Jak 1.
