Crash - all three games are great especially the third and their amazing cart spin off
Jak and Daxter- I enjoyed the 2 and 3rd entries more than the first because the shooting and racing added even more variety to an experience that already had plenty.
LBP - Awesome game. I thought even the singleplayer was awesome but having 3 or 4 friends in the room to play with made it even more awesome. I still pop it in occasionally to see what strange things people have made. Playing user levels with friends is amazing.
Locco Rocco- It's gorgeous and it's tunes put an instant smile on my face. I love whimsically bouncing around and trying to find all the secrets.
Tomba - Some of the best and most overlooked platforming on the original playstation. Anyone who calls themselves a platform fan owe it to themselves to track it down and give it a try.
Megaman/X - If pure awesome were to have a child it would be this series of games. Tough platforming and twitch action.
Castlevania - only the newer styled SOTN Metroidvania ones but they are so awesome. Mazelike gameplay with rich art direction abounds. Music especially in SoTN.
Metroid- Great music great exploration and sense of lonliness
Uncharted - I play through the shooting sections to climb around and explore the next tombs. I wish they would focus on that part of the gameplay only or at least more.
Ico/Shadow of the colossus - I can't cite games more different from anything else I've ever played. Unique and wonderful. I feel almost ashamed to simply call them platformers.
