It would be really cool if a torch thing was built at /warp events and/or /warp pvpgames that was lit by someone upon the begging of the games ;D The person that lights it could be chosen random pick of the winners of games the previous week. Or maybe there could be a lottery and then winner gets to light the torch starting the games. Idk if it is possible, but the torch could be lit by a sign which also awards the lighter a prize! Of course the sign area would have to be sealed off after it is used.
Or now with script block we could have a sign in the control room that shoots lightning at the desired location!
I say you pick someone randomly every time to walk up and pull a lever to light a big netherrack surface
