$60 midnight release for Portal 2 on 360. Overnight I beat co-op with a friend and once you do it once, there's no point doing again with someone new concurring with what yahtzee said. The single player was massively entertaining but with a puzzle game there's really no replay value. Once you know how to do it, there really isn't another way to do it. Bioshock you could go through and do lots of different things by comparison. So for 60$ to someone who could barely afford a game he anticipates once every three months, I felt no guilt turning it back in within a week to scrape back bits and pieces of it.
The kicker which makes this the worst? I don't recall detail but I believe it was a weekend or two after it came out, they dropped the new price 20$ making it $40 . . . wtf.
