Brothers looks really good, I might give that a try.
I've been playing From Dust, downloaded it ages ago and am just getting round to it. Love the idea, love the graphics, love the physics, hate the AI. It's ruining the game.
Seriously, the AI is terrible. I spent about an hour using lava to build walls to protect my people, then to build a nice pathway across the water, diverting waterfalls and lava flow, and what do my people do? Half of them refuse to walk along a simple pathway and move the opposite direction when I tell them to get to their goal. The others, well, one managed to get all the way across the map only to decide to stand still saying 'help' when he's three feet from the exit, and another got to the exit, then decided to run past it and up the side of a volcano. Truly terrible AI.
