Is 256GB Enough for Bootcamping

I'm currently thinking about getting the new "retina" MBP, but I know that I will be using Windows on it. I definitely don't want to shell out the extra money for the more expensive option because 256gb more storage and a slightly faster cpu are not worth another $600. Would the existing 256gb be enough for me? I am a rising freshman in college and plan to use the Windows partition almost exclusively for games(SC2, BF3, Portal, TF2, Shogun 2) and OSX for everything else. If it is not enough, I will probably get the normal MBP 15 or another laptop(Series 7, Envy 15, ThinkPad T430, and SE are contenders) and swap out for a 480GB SSD.
