Can't have an MK game without flawed fighting, so here's what I've found thus far.

- when attempting to dash in and do a regular attack, the CPU will still think you're tapping f,f unless you completely stop, and even then, it doesn't always work. I made the mistake of trying to dash in with characters like Liu Kang, and when I try to uppercut, his flying kick comes out. It's VERY crippling for dash-in juggles or quick surprise attacks since the moves get confused.

- Green lantern also has a weird issue with his d,b 2 attack. It comes out many times if you just dash in and duck with 2, even if you delay the button press. It pretty much leaves GL WIDE open, since that attack only hits characters who are distanced.

- Aside from the "Test Your Might" the mini-games suck. They take away all forms of skill and turn it into a guessing game. Nothing like being 2 hits away from victory, only to be outdone by someone because I'm not a mind reader...it's all luck-based. Freefall is also busted since you can get a lucky hit or 2, then just stop, and the opponent can't do anything to counter unless you're attacking, so they fall and take the damage with no other possibility of countering.

Many of the more complicated pro-moves are completely useless, like Deathstroke's and Superman's. They require an AMAZING level of timing and leave a very little window to perform. The slight increase in damage isn't worth the effort at all for many of these.

- The breaker system, while fixed up a bit from the previous games, is still broken. It would've been better as something like an alpha counter or a parry, where it only works on incoming initial attacks. It also has a knack of only working when it wants to. Countless times, I've had a full rage bar, only to be jamming on the breaker command while on the receiving end of a long combo.

- The AI loves to somehow break the rules of Mortal Kombat. Not only does it start off with half a rage bar already, it can, on random occasions, not only initiate rage mode from the start of round 1, but can also do breakers while in rage mode. I don't get it.

It's also fun to get decimated by AI opponents who use Freefall and Klose Kombat, since there's no way of telling if they're reading your input or not. From the way the AI behaves during regular combat, it wouldn't surprise me at all (remember the "dancing" AI from UMK3?).

The game is still immensely fun, but these problems were pretty noticeable to me.
