Yeah, either way don't think I'll be getting it, probably get Torchlight 2 when it comes out since it'll have 4 player co-op.
I completed Portal again yesterday, just so I could hear the song again... despite it being on YouTube. http://www.youtube.com/watch?v=Y6ljFaKRTrI
I think I'm going to try finishing those on the Currently Playing list first before I even start any new ones, Batman first or Half-Life, then BioShock and Darksiders.
Also, Steam is doing a 4 day sale of 2K Games, today it's Mafia 2 for 75% off and the other sales will most likely either be BioShock, Borderlands or maybe Civilizations V at the end (I'm hoping anyway). http://store.steampowered.com/sale/2kgamesmafia
