Also, I'm pretty sure Pride has one 10 minute round then one 5 minute, with a 5 minute tie breaker if need be.

Also, Pride judges based on who won the fight, not who won the most rounds. I think this is a MUCH better way of judging. If Fighter A lays on Fighter B for two rounds to win them, but then Fighter B cuts up Fighter A and breaks his face and bruises the hell out of him and takes out his legs and grounds and pounds him in the third round, Fighter A would win in UFC while Fighter B would win in Pride.

Also, be aware that Pride can't use their normal rules when the show is held in America, as the fights are sanctioned by whichever Athletic Commision runs the state the event is held in. So in the American shows, there are no kicks to downed opponents and elbows are allowed (if Pride chooses to allow, they may still not allow it just because the they don't like them).

And another major difference is the whole Cage vs Ring thing...it may not seem like much, but the cage can become like a third guy stepping in the fight sometimes, to help better pin a downed or standing opponent.
