Hahahah, I love it! It's been doing the rounds as a flash/mobile game but this is the first I've heard of it. Out today on XBLA. At first I thought "is that it?" but I see there is some depth to the gameplay - trying to get the tower blocks exactly on top of each other, building the right towers in the right locations to maximise the population, etc. All in all very engrossing. Anyone else bought it?
