Instead making bricks we could make a event for a brick.
A event that once used (i.e. onActivate > Client > Opengui > [game name]) will open a gui and people can play in there, gui is shared. So if you click the brick, do something on the gui then get out of the brick another guy can come and see the exactly same thing you did.
I am not sure if that's possible either, but hey, it's a better idea than 2000k events.
