Here's a really nice teaser trailer for Risen 2: Dark Waters. This minute-and-a-bit of footage is more exciting than anything I found in my first (and only) hour of the first game. So, that's a good start!
I'm pretty keen on checking this game out. The first definitely had promise, but it was very weirdly designed and felt like a hassle to play. If they make this one more convenient to enjoy, it'll be a fine RPG.
