I was thinking how cool it would be if there was a team rocket guild that let you run around in the team rocket outfit from HG/SS, and I'm wondering how difficult it would be to implement that feature. Kinda like the guild tabards from WoW, a guild member could choose to wear a "guild signature" that marks their overworld sprite with some symbol, or a full sprite revamp that other people could see. Not sure if this is a good idea, or a practical one, but I like it. Of course, guilds aren't even implemented yet, but it's a thought.
