I'm a big combat guy, if the combat is fun and deep(read, not mashing one button till everything in the room is dead) then I'll see it through to the end, even if I have to consult a walkthrough for the puzzle parts.
A good example is God of war 2, titan mode. If you didn't pay attention and actually learn how to use your abilities, you would die, alot(which you will anyway, but it lessens it) but the puzzle parts bored me to death and I just wanted to get back to the combat, so I had someone tell me how to do them.
