Mass Effect 3 multiplayer
Oh my gosh, so much fun. I thought it couldn't get more fun, and then I played as a krogan. I have yet to unlock any of the other aliens, but I've seen most of them in action (flippy cartwheely drell!) and they are amazing. If you haven't tried multiplayer yet, I'd really reccommend it!
Unless you have anything you need to get done, of course :p
