I adore Terra Nil. I played it before release at PAX and I was hooked. As someone with unholy amounts of hours in factory building games, this is such a gentle palette cleanser.

The one thing others have pointed out is that it is a pretty short game. I'm nearing 100% on it - which i should complete in under 8 hours. I honestly don't mind that. Not every game needs to be 100 hours of playtime. I spend as much as I did on this game to go see a movie that lasts 2-3 hours, so I won't complain about the price for the game.

If that's your hangup, wait for a sale and pick it up right away,
