Hey guys, I need your opinion on the matter. I want to play each of these games, genre doesn't matter. They are placed in the order of how much I want to play them, but I think I will end up playing all of them eventually.
  
The Whitcher - PC
Lead and Gold - PC (or 360 when its out for it) 
Heavy Rain - PS3  
Borderlands - 360/ps3 (probably will play alone) 

not much of a blog post, but whatever. The Witcher is the best out of those four.

Heavy Rain can be finished in one sitting whereas the rest of those games will take some time. Since everyone owes it to themselves to experience Heavy Rain, you'd be better off just plowing through it in a day or two then deciding which of those remaining 3 to play.
