Heavy Barrel and Ikari Warriors probably took more of my quarters than any other arcade game.

Zaxxon please!

Another arcade beat em up would be nice besides TMNT like X-Men, Aliens vs. Predators, or Simpsons.

Ikari Warriors would be a big one for me.

I wouldn't mind seeing something like 1941/42/43 come out on Arcade.

Tempest ........... PLEASE!

No more arcade remakes, please. I can play them on MAME with my X-Arcade.

another vote for Tempest

What about Zaxxon? Come on!

I'd love to see a four player game show. Something like "You Dont Know Jack"

Ohhhhhh man there are too many.

Killer Instinct
Mortal Kombat II (NOT 3, 2 was the best!)
Virtua Fighter
Donkey Kong Jr (HA, that's not going to happen)
Michael Jackson Thriller
Ninja Gaiden
Strider

I know there are others, but man this would be awesome!
