I got the paradox bundle, so I have a few of their other games. I've tried magicka, which I thought was fun, but I hate the control system because its so hard to get used to. I played a little dungeonland, but that's more of a multiplayer game and I haven't played it with other people yet. Warlock: Master of the Arcane is fun, and one of the few games I can run well on my laptop, so it my go to game for trips and stuff.
I want to get EUIV eventually, that looks like it would be fun.
