I like most Source games. Portal was epic. (The Cake is a lie. ) Half-Life 2 is awesome with the physics. Left 4 Dead 2 was alright, but still great engine. Garry's Mod is also great if you can get past the 4chan-esque community behind it (okay, maybe not QUITE that bad, but still pretty horrible). I really like doing NPC wars and changing their models. Though, things get a bit glitchy when you start doing really crazy mixes like taking an antlion model and assigning it to a Combine.
