Only time knockouts are annoying is in football or soccer takes to long to revive. there should be a scale games that have longer fields you get a stamina increase! (for running)
In ice breaker/ lchiban once you been knocked out once, there should be a few seconds that you get can recover and escape (fighting chance) like when its you against three of the opposing team! IE stun gun gives your resilence once you been shocked to many times
