Enki said in Pre-match timer:

level.gracePeriod level.prematchPeriod level.inGracePeriod

you can play around with this variables
but they can cause some problems for example on our tsd server sometimes the game dont end if you hit a shot

You can make the level thread a function that sets those variables in a loop and then ends on game_ended.

As im not experienced at bo2 i cant help much but i can help with some traces:

1- there should be some event handler probably named endGame(its from mw2)
you can call your start voting script from. it may be in any of _gamelogic or _globallogic

2- you can use good old voting script from Cod4 Royal Soldiers HC mod(available on cfgfactory) however its not as same as design of what you just sent

3- and according to ImVeryTwisted if bo2 using old maprotation system (not the random one) you can easily set sv_mapRotationCurrent dvar after voting completed

hope i helped you. sincerely

H3X1C Could it be the sheer size of the script, because I haven't changed anything groundbreaking?
