Actually, there are several features that make me want this game, and one in particular :
I CAN FINALLY TRAIN PROPERLY !!

No more bullshit training mode from MK9 where you can't even calculate the priority of the moves or make the AI do a specific attack.

The ability to record the moves of the AI and reproduces tons of scenarios is amazing. It's essential in fighting games.
And now, there is finally a frame data to make everything more accurate.
YAY!!

And you, what is the ONE (... Ok, you can write several things if you want!) that gave you a pleasant surprise ?
