I originally tried to get it, but couldn't find it on PC so I got the 2nd one. It is kinda entertaining but I got bored somewhere down the line and haven't finished it yet. Maybe I should get someone to join me in co-op and try to finish it that way... Have never played a game like this in co-op.
Left 4 Dead 2 didn't impress me... I played for a few minutes and then got angry with myself for paying full price (or close to it) for "that".
