So I tried out some demos yesterday, and here's my initial thoughts on them:

Citizens of Earth: This was a pretty fun one, particularly some of the bits of dialog between the different characters. The battle system looked easy enough to use, definitely putting this game on my wishlist.

Monster Hunter 4 Ultimate: I'm about as bad at this one as I was with the other Monster Hunter demo I tried out, but I had just about as much fun with it as well. Maybe I'll get the full game eventually.

Also had another pleasant reminder of how bad my luck tends to be in games where my brother showed me some of his custom characters in Smash and was puzzled that even though I've been playing more than him, I have weaker characters overall. Oh well, that's just how it goes I guess.
