I heard about the game around 4 years ago.I paid the full $60 for it in February and waited...and waited.... and then they pushed the release date back...Then I finally got to play it. and it was well worth the $60 and the 4 year wait. $43 and no wait? Do it.
I've got a pair of X1's I love, My brother bought the X31's but he has to turn off his wireless router when he plays because they pick up so much static.
