The trouble with putting tough action sequences in RPGs, sims, and puzzle games is that not every gamer has spaz-like thumb reflexes. It's the nature of action games to try to defeat the player and force him/her to start over, a throwback to the days of quarter-munching arcade machines. The problem is that these action sequences are distracting gamers and do little more than pile on the frustration and force us to throw a controller through the wall.
Should action games stick to their own genre and leave brainy games alone? And if not, do you think action games as a whole are too difficult?
