I finally got a chance to play the demo for NEO Scavenger the other night. I like it a lot. There's a lot of tension, as you need to balance your different needs to stay alive (food, water, staying warm, etc.). Do I eat that mushroom that could be poisonous to keep from starving? Do I fight this bandit who's chasing me, or do I try to run away? The combat is kind of like Dwarf Fortress, in that instead of hit points, you get injuries to body parts which affect your abilities to do things. Unlike DF though, you get to control what you do in each round of combat. I'll definitely be buying this game at some point.
Oh, and to keep this somewhat on forum topic, I'm really looking forward to BD. I'm not in the alpha, but I've been following the development, and it looks like it's going to be really good.
