Correct, but this option will be added in AG3 for Reputation

Eh. If anything, it'll make comparing your scores to people who have a similar interest in a game easier. Besides, not all clans might be for flash games: They might be for Pittsburgh Steelers Appreciation, or a group for a certain band. Scores in games reflect an individual's skill in that game; I don't see how having clans would affect that in any way.
