Right now I am currently playing Zack and Wiki (etc) on Wii and just (finally) got through the "Frost Breath" level.
On 360 I am playing Lego Indiana Jones.
On PS2 I am playing Sly Cooper 3.
On PC I am in the middle of games of Curse of Monkey Island and Sam and Max Hit the Road, although I'm not actively playing them right now.
On DS I'm about to start playing Jake Hunter: Detective Chronicles.
Gee, and to think two years ago I didn't own any consoles....
