You know the drill- in one or two sentences, pitch a genuinely good/addictive game to us in the worst way possible. I'll go first:
Mario To win, you press the jump button a lot, I suppose.
Half-Life So you're this scientist, right, and then you get a crowbar... Profit.
Frogger An amphibian tries to return to his home in the river. He can't swim.
Animal Crossing You move into a town populated by all these animals, and... uh...
Minecraft To do anything you have to chop blocks away. For hours.
We Love Katamari... uhh... um... glue?
