regular brick damage is: destroy a brick, and it fakekills for a set period of time
what would be neat is a server mod where instead, brick damage destroys the brick permanently
(probably by deleting the brick, but without destroying anything on top of it)
should only work in minigames, but if that's not possible, then whatever
so you can have a deathmatch which starts out as a city but ends up as ruins and rubble
