Played a lot of STALKER: Call of Pripyat with the Call of Pripyat Complete mod.
It does a re haul of the graphics making it appear much smoother as well as adding better sound effects and guitar songs. The guitar songs seem like a small thing but when you only hear the same thing over and over again it gets annoying fast. So basically it makes the game prettier and adds to the immersion without changing the story. Stalker is basically like what Fallout: New Vegas tried to do with hardcore mode, but Stalker got it right (and first).
Also played Minecraft on a multiplayer server with some friends. Notch has a lot of work to do because survival multiplayer is still buggy as hell. Speaking of that the Nether still doesn't work. -__-
After STALKER and Minecraft I messed around in Just Cause 2 some more. The perfect game to hop on with on intention of doing anything productive and having a blast at the same time.
I'm thinking about getting Amnesia: Alone in the Dark
Could be interesting but I wouldn't get around to playing it until sometime next month.
