you know what would be awesome, maybe as an external add-on?
countdowns, voice acting, pre-round buildup.
at the beginning of every match, players are locked in place in third person, and a voice counts down from 5 (though the timer can, feasibly, go much higher) to 'go', at which point all players are given control of their characters and chaos ensues
then there can be announcements for time- minutes, seconds. "1 minute remaining!" "2 minutes remaining!" "3 minutes remaining!" with some randomization between voice clip selection, culminating in another 5 second countdown to "GAME!"
