If you took all the eye candy out of Travian....you'd be left with this game. It's an interesting twist where you live your life as a 'row' in a database and your goal is to raid other rows via sql queries and expand your empire by inserting into other rows....(Geek Street Cred ++ ).
Pros: It's easy to get into and the interface is very simplistic. No hidden formulas, fast pace (at least in the beginning).
Cons: Missing certain functionality such as conquering other villages and has too many carebear anti-farming measures (your can only attack rows within a certain range of your attack rating versus their defense rating and you never lose anything you build)
Ugly: Since you get resources every 10 seconds, you might get sucked into constantly refreshing/timing when you should make your next move....don't get sucked in!
