As a suggestion, since you have all kinds of cool names for the achievements (Mission: Impossible) for different games, I would love to see it a little more organized with possible the game name in the achievement name.

So something like:

Knight Fight - Mission: Impossible
Knight Fight - Double defeat
Knight Fight - Path of twins
Knight Fight - Galloper
Gammon - Stick around
Gammon - My three sixes
Gammon - Double strike

... it's well organized in a persons profile, but if I go to the Achievements page and use the drop down, it's hard to know which achievement is for which game.
