Another thing to watch in the beginning options is using the semi-colon. ; That means the rest of the line is a comment and will be ignored. So all of those timer settings and max players are being ignored.

Setup custom variants with all your specific settings (weapons, vehicles, game options, etc), then setup your actual match lists at the bottom, just as Johny has it laid out. Notice a 'custom variant' actually has a 'custom name' as well. So dont say 'Team Slayer' and think yu can change the rules. Call it 'My Team Slayer25', then set all of the options you want for that game.

The match is a pretty quick association of the 'game type/custom variant' and map. The server will reference all the rules within custom variant.
