Haha forgot noone outside britain would know of British Bulldog. Sorry bout that. It's like tag but with two safe zones, like rugby or American football touchdown areas. You run from one side of the pitch to the other and one person has to catch everyone as they run from safe zone to safe zone. If you get caught you join the Bulldog's. The winner is the last person standing. There are varying levels of violence involved. Sometimes you just tag them, sometimes grab for several seconds, in others you tackle them to the ground and pin them down. All good fun. So like that in Dota.
Edit: Liking those ideas G.ZZZ, the RPG thing had occured to me, I imagine it would take ages though.
