Game: Island Empire

Island Empire is a social city building game that essentially plays like a nautical version of Haypi Kingdom. You build things and collect resources as you attempt to build up a prosperous port town, and you can both join forces with other players and attack them depending on your mood. Aside from the theme, there's little to differentiate Island Empire from all of the other menu-driven city building sims on the iPhone. Which isn't to say that it's bad, it's just lacking much in the way of original ideas.
