I suppose you can call my gundam roleplay a sort of Tavern based rp. Everyone's stuck on a ship or they're going to be forced to go find somewhere else to go and then the people they find may not even want them. So they're all forced to work together to get through all of this mess they are in. Tavern meet ups aren't really unique most of the time but it's a simple way to get everyone together and it's better than just having the characters meet up in a street and saying 'sup guys time to go on a quest because fuck it whatever the bad guy is doing is bad."
