None where really difficult to me, but MK Trilogy was difficult for me to except that some characters where missing fatalitys and even stage fatalitys. I wish they would of made that game complete.

MK games difficult....maybe the first time you play them,but after that all of them are a piece of cake,all MK games have tips and strategies to rape the machine all over.

Mk2 for some reason. Especially hard as a special feature on MKSM.

MKII

Mortal Kombat II, MK Trilogy and Mythologies: Sub-Zero

I find it incredibly annoying how the CPU always manages to throw you first, throw you right before you attempt a sweep, and always dodge your uppercuts to deliver one of their own. Oh yeah, and everytime you flip backward they throw a projectile and hits you right on, or if you flip forward they always attack you first some how. Fucking retarded AI.

The only way to really "rape" the AI in MK is if you study its weaknesses enough to know what attacks do what - and that is what made MK really lame. But nothing is ever as hard as playing a real person. The possibilities in a human fight are endless which makes it less boring.
