I have a Wii, a Gameboy Color and a Gameboy Advance SP (although if I want to play Color or GBA games I'll go to an emulator before my own systems), and then my 3DS. My brother has an Xbox 360, but I only get to play that once in a blue moon (I got Catherine not long after it came out and am still on my first run ahaha).
It would be hard to list all the games I own, but the ones I've been playing recently are Pokémon obviously, 999, Golden Sun, and Harvest Moon DS Cute.
