To a drummer, anything under the highest challenge ranking possible would probably be boring.
Playing something exactly the way another drummer played it violates an unwritten rule among drummers. Even when I play covers I try to recreate the general affect, but I'm not going to sweat every single bass drum note and I'm certainly not going to play note-for-note fills unless it's absolutely necessary (i.e. the big tom fill in In the Air Tonight or some signature fill in a Rush song). In most cases what I play is more complicated than the original part ... studio drum parts are dumbed down so the masses can relate to the rhyhtm better ... live shows typically have the drummer playing something more ... involved.
So the game is not only a challenge to people who already drum, it's irritating because it demands perfect reproduction. I p*** on that mentality!
