yes the one room thing is in all games and actually slowly fills people with rage... stuck as spectators waiting for the sole room to finish the current game.. forced to endure the obvious mistakes and missed opportunities.. get banned for telling a noob he shouldnt make a nuke silo at 3 seconds in.....
multiple rooms leads to clans .. clans are just too op.. and soon everyone is in fear
that is why clan balance is illegal in most countries
