It was on sale 33% off in December I think. I'm personally waiting for a 600 MSP sale, it looks right up my alley.
I say wait for a sale because as soon as you buy it full price, it'll go on sale the next day.
Haha how often do games go on sale? Like is the average one a year? Maybe Twice? OR is it random? --- Will not change this sig, until Carlito is a World Champion! 7/10/11 (Unofficial Date: 6/11/05) R.I.P Shauwk, Gone but Never Forgotten. You will be missed.
There are weekly sales but it'll usually be the games nobody wants but there is sometimes a gem hidden among them though and you have special holiday/thanksgiving/black friday etc etc sales --- Big Apple, 3 A.M. http://i.imgur.com/wdoDMOo.gif
