From Dust is a creative and interesting god-game/strategy game. It's sort of an update on Populous. Way better looking than Populous, though.
I enjoyed playing From Dust through about half of the game's missions. Figuring out how to manipulate the environment to advance your tribe through a series of goals is fun and challenging. But after about 5 levels, the game's challenge became less about figuring out a strategy, and more about executing it with the awkward controller scheme. After about 8-10 levels, it just became too awkward to play. The strategy elements of the game outgrew their clumsy control scheme.
I might recommend this, though, if it's on deep sale. It's pretty to look at, and I had a good couple of hours of fun before deciding the juice wasn't worth the squeeze.
...That damned level with the burning trees. Gah.
