Bat-tastic
This is a perfect example of what great, sidescrolling classics on the NES were all about. I was only 2 years old at the time (I'm a young'un), but I can still vaguely remember the buzz as the older kids rushed home from the cinemas after seeing the Batman movie for the eighth time, proceeding to huddle around their TVs, pop this little sucker into the NES, and go to town for an hour or three. I've never beaten the Joker, but I've gotten close! During the final fight, though, I hope there's a built-in voice chip that makes Joker continuously wonder aloud as to where Batman acquired all of his delightful gadgets.
