Hey, first I just wanted to say I love these tilesets a lot you really do have just about everything.
I was wondering if I'm planning on working on a game in a group, would each member need to buy/download of the tilesets? Just asking because apparently that's a requirement that some asset creators have. That being said, for the foreseeable future, I'd be the only one actually doing the dev work on RPG maker and using/editing the tileset.
