I like SF as you can tune the difficulty to your own expertise with the game. So you could go stupidly hard and tune it to the highest Difficulty. Or tune it down if you just want an evenly matched fight.
Although I dont own MKDA, Ive played it and its simplicity is painful. Firstly the AI dont actually surprise you with any Attack. They would just be walking towards you mashing X,X as it would seem and that for one made the game easy seeing as you can use all this to your advantage.
Thus, even with MK's option for players to choose 1 of 3 stances for a character, each stance changes little about how you use the character. Seems like it was added in for some brownie points with people who complain that the game was maybe too simplistic and that it would heat up gameplay more, well it didnt.
Also, even with characters moves looking authentic and all, they still seem to move like robots.
