Ill start with the bad stuff
No jostling on the ground to isolate certain limbs, no clinch against the cage and subs just come by the press of the RS so it may well be the same everytime depending if your in full and half guard, side control, mount or have thier back, so thats 5 submissions but like i said ages ago i cant see them ever getting a game that can fully represent the battle of a real MMA fight.
How can makers make variables for defending? like if your dominating on top and let a arm go stray for a armbar or the guy on the bottom pulls his leg over the shoulder for a triangle or something like the feeling that your really struggling to get off your back or out of the clinch? Either there isn't enough buttons or it will be far to complicated to play.
Thats the bad part of it, now onto the better stuff.
All UFC fans will love this game, its more arcadey than realistic but it still feels awesome KO'ing someone or even dominating them on the ground and its that authentic you with think your watching a PPV at times. The AI must be on easy though because you can pass guard at will but i still had some great matches none the less.
In one i had Shogun in full mount, he spun onto his back to try and get out so i went back to full mount again after i gave him a few punches, once again he tried to get out of it by giving up his back so i went to full mount again and rained down punches for the TKO. while that may not sound much the feeling of dominating him and making the right decisions felt awesome and Multiplayer may well bring this game into its own, with its counters and blocking and chalk off some of the bad points above because it wont be easy to take down or keep a human and a harder AI opponent on his back and they have gave what i said about subs from the bottom a good go by using countering, so if the guy on top throws a punch correct timing will counter it but that's not exactly how if works in real fights, but its there in some form
I hope that gives a insight into it but i bet it doesn't make sense for the most part

anyway UFC fans will love it and i cant wait for the full game
if you have any questions about the stuff i have put feel free to ask
