I've had countless discussions with people on both EA and THQ forums about this being in an MMA video game.
While mini-games such as what Undisputed 3 and EA MMA featured are the simplest concept, it takes away some of the realism that many fans love.
So, this new concept doesn't 100 percent eliminate the mini-games, but it makes the actual act of going after and getting a submission much more realistic.
In all the current games, you click one button, and you're in a submission. I think that's like having one button that knocks your opponent out—and that's definitely not realistic. So, EA UFC should make it to where you have to, first, get a hold of a limb.
For example, gain wrist control, get rubber guard, trap your opponent's leg, pull your opponent close to your body, and more actual things that usually happen in MMA when setting up a submission.
Next, you transition to your submission. That would depend on your window of opportunity (because if I notice you're grabbing my wrist, I'm going to jerk it away) as well as yours and your opponent's submissions stats.
Next, the mini-game. The mini-game should be a little simpler in this situation because you've already done most the work, therefore it shouldn't be impossible to win. At the same time, though, if your opponent has 85 or above sub defense, he should still have a chance to escape.
It may seem like a lot, but in my opinion, this would upgrade both the submission system as well as the game's overall realism.
