Imagine you're invited over to friend's place to watch Willy Wonka i.e. Charlie and the Chocolate Factory. You know Willy Wonka, you really enjoy it and you're totally ready to sing along to "Pure Imagination" (in your head) with Gene Wilder for the umpteenth time. But, when you show up, it's the Johnny Depp version. It's still great, but you don't really know it as well. That was my Battlefield 3 E3 preview experience.
