The ones you name are already a great start, but if you want some more;
* Fire Emblem Radiant Dawn. Very harcore SRPG
* Okami and RE4 if you haven't played those earlier
* Zack and Wiki is a great point & click game
* Tales of Symphonia 2 if you like JRPGs
* World of Goo and Boom Blox are great puzzlers
* Wario Land and LostWinds are great 2D platformers
* BlastWorks and Geometry Wars are great Arcade shooters
* House o/t Dead 2+3 / Ghost Squad / RE:UC if you like lightgun shooters
* deBlob (platformer)
* Shaun White Snowboarding
