any game that requires high manual dexterity. fighting games, beat em ups, shmups, "hardcore" platformers, you name it. it's not that i think these games are bad, i just can't play them.
This is an interesting point you raise! I think balancing the dexterity of input versus the on-screen output is a delicate art and it's really quite difficult to get it right.
I initially thought that the more I played KoF, the more I would get the timing for the inputs, but it didn't really happen for me. And then there was Rising Thunder which ... 'abstracted' (for lack of a better word) the inputs and I thought was a very neat execution, and really broke down how fighting games sort of work for me? I actually got a bit better at KoF after 'getting' Rising Thunder.
Just a thought I had.
