Idea:
Badges: You earn badges by doing certain things, like getting all the items in an advanced game (e.g. the Wal*Mart Award)
Rankings: By doing enough of something, or reciving a certain ranking on a game, your ranking increases.
Pros: Encourages better games, by creating custom badges for your game, they may be more popular
Cons: People may feel left out if they can't achieve a higher rank or get badges.
Uses: High ranking people could get access to a picture gallery, get to use games with hidden links (see my previous post), earn multiplied MAG points, and get access to more duels
