[Since we have two lives each, I think to me the time limit should be 10mins.
Why? because if we play GB(GameBattles) the time limit for Domination, TDM, is 10 mins.
Example: If we play Search and there's 60 sec left, two people left, you how search goes right? They'll get nervous all that. In this FFA(Free For All) that were doing, 60 sec left and two people left, there gonna be nervous(well not really) when time is ticking...get it?.
They'll *Experience* that and they'll improve their gameplay.
