I think this would be a great idea, to have unlockable ones. It would be good to have ones based off of popular games, like the Charles P. Sheepton one. Maybe these could be unlocked by achievements from the game ...?
i think that they should have one so that it looks like AG2
Good idea, but a little off-topic.
What's the point of having unlockable skins? Who's going to know if you have an unlockable skin anyways? It's not like Armatars where you can show off your activeness in a nice way.
I think we should automatically get them, as they aren't a big deal. Skins are just novelties anyways.
