You know what I loved most about the first two Monkey Island games? The art style and colour palette were so damn sunny. Other games, like Far Cry, have tried to do the same, but they never felt like a summer's breeze in quite the way Monkey Island (and particularly Monkey Island 2) did.
Assassin's Creed IV is nailing it though. I watched this all the way through, and there are sharks in it, that's how much I liked it.
