Upgrade Complete: game whose objective is to upgrade the game

Upgrade Complete is an hilarious Flash-game where the objective is to complete all the upgrades needed to play the game. I haven't had this much fun since I spent three days downloading a 50GB World of Warcraft "upgrade" that made the game stop running! Better even than spending a week patching Black and White! A wonderful homage to games like Achievement Unlocked.
