It's pretty shitty. Wish I didn't spend the money on it since all I really wanted was MK2. I was playing online with my friend and the connection we had was terrible. I spent MANY hours as a kid playing MK2 and 3 on the SNES version of X-Band and both of them ran ten times better then the MKAK. They say their working on a patch, but after that one announcement I haven't heard anything.
The game emulation is weird. If you want to look up your character's moves, you can't be between rounds. After you check your moves and go back into the game you don't get control of your character for a few seconds. I was trying to do the look up a fatality then do it, but my character would just stand there and the time to do it runs out. I'd be nice if you could change the options in the game to allow for more time to do a fatality. It seems less then five seconds in UMK3, if you're not where they want you to be you can forget about doing it. I also hated you can't use kombat kodes and in order to unlock the other three characters in UMK3, you have to have a second player, but for some stupid reason if you play an online game, all three of them are there to use.
