There are games that are not worth mastering, certainly. There are games that are difficult to master, but richly rewarding to the hardcore audience. And then there are games that are so popular everyone wants to master them, including people who can't really be bothered to put in the effort to do so.
Innovation Technologies decided to help such wannabes out by producing a special controller for the SNES and Genesis versions of Mortal Kombat II -- with the special move sets built in as preprogrammed macros. Drop $49.95, hit one of the special "Mortal Activator" buttons, and voila -- instant mad skillz. No need to mess around with actually learning to execute the special moves and fatalities.
I guess it's kind of hardcore to spend fifty bucks for a controller dedicated to a specific game.
But buying the illusion of talent you don't actually possess -- that's just old-fashioned cheating.
