Just finished Two Worlds II (for the PC) yesterday.  My feelings on it are fairly complex, my review goes into it in more detail here.  I also just downloaded the new Back to the Future episode.  I'm about 45 minutes into it now, and it feels more or less like the last one, so I expect I'll like it just as much (review here).  I've been playing Magicka some as well.  I haven't beaten it yet, but that's not for lack of wanting to.  The game is a blast to play with friends.  It's a lot of fun just blowing each other up, reviving, and repeating.  Well worth the cost.
