OK, just for fun: Donkey Kong II was a hit, so what other arcade titles would you love to see a creative hack for? Here's mine-
1. Robotron 2085- the exact same as Robotron 2084, only 2 player (for all those folks who have a Smash TV/Total Carnage setup).
2. A version of Joust where a power up lets you ride the pterodactyl. Ride. The. Pterodactyl. And different level setups, beyond the disappearing platforms (but not like Joust 2-blah).
