as thinking of someone making in-game worlds and have camera over_rides such as if it is a 2d game - camera pans out and goes to side view.
the avi plays as the MC in the game.
playing super mario64? your avi replaces mario and there are teleports under the pictures to the levels.
but would it just be a cluster of people? set a time thingy like;
>please wait [time left] while [name] is playing
and if person leaves game, the next person joins.
