So I was playing Worms 2: Armageddon and noticed that Avatars come up in your turns, doing whatever it is they do. But when I go to the Xbox Live marketplace, under the "Avatar Games" section, Worms 2 isn't listed there. Is there a reason it's not there?

The game isn´t really an avatar based game. It´s a strategy game which just makes use of avatars during turns (if they decide to appear, sometimes they don´t) and is just what you could call eye candy.

Hence why W2A is not listed in avatar games

Avatar games probably do more then just "show them on-screen for 5 seconds".

that's all bomberman does but that is in the avatar games

Speaking of the avatar, during one game my damn avatar got stuck on the screen and was literally blocking some of the action... I imagine that was a bug?
