If you host a pvp game an option to set player damage would be good.
it could be set lower to make fights last longer instead of the insta death
or higher if you like one hit kills
anyone who joins your pvp room will see the set options on the team select screen

other options could be

timer
team colours

or even what hazzards you want on the map
barrels ao3
barrels fh
firetraps bs
sandtraps ssc
toxic gas swamps
silkroot plants fh
ect.
