I have seen videos from the new MK , DOA5 , VF5FS , MVC3 , they all seems difficult to me. The problem is, there are few types of combos in TTT2 and you have to remember many moves. With helping tools like manuals or better practice modes the game can be more friendly for most of us. I believe in general the fighting games are difficult , mostly because we have to learn many things on our own and spend hours practicing, only if we dont rely on helping tools like game guides etc.
