World War 2 roleplay anyone?
Why not some kind of shooting RPG gamemode, like the one where you can buy weapons and armor and each come with different stats. Also include some type of upgrade system with a trading/auction house feature to trade with others.There was some community that had this gamemode perfectly planned out, just with bad execution. I can't for the life of me remember what it was called, but it was popular about a year ago.EDIT: Gangs of Glory was what it was called. You can see a video of it here. It seems they're in development of their updated version, but we could derive something off of this. It's a lot of fun.
How about RefugeeRP? You start as a guy in a war torn country, you can buy a boat and smuggle people, with the risk of dieing and losing your boat, try to find a good country, go into an Asylum and RP jail type things, or be the military fighting.
