You didn't 100% a game based around 4,000+(and growing!) pieces of content and leaderboard ranks. You got all the Achievements. That's very different. Come back when you're #1 on every song ever released, have the most Cred of everyone who owns the game, and when you have let's say seven digits of Coins, THEN we can discuss if you '100%'d' it.

There are no platinums for downloaded games (except for downloadable versions of full retail games).
