I have a hard time picking favorites so here are mine in no particular order: Skyrim Mass Effect (series) Star Wars: Knights of the Old Republic (1 and 2) Pokemon Crystal (and the Heartgold remake) Halo 2 (3 for multiplayer) Far Cry 3 (and Blood Dragon) Dark Souls Dishonored Super Smash Bros. (series) Assassin's Creed Brotherhood There are other great games I've played, of course, but these are the ones that come to mind.
