Back in my hometown, we had an awesome arcade called Dodge City - it was one of those flat-rate free-play arcades that only stocked older games. I didn't realize it at the time, but the owner of that place really knew his games and he had an amazing collection (including that Tron disc booth thing!).
That being said, I didn't spend much time in arcades growing up and Dodge City closed down around the time I was old enough to pay the daily rate myself. Help me live vicariously - what were your favorite arcade games?
In my limited experience:
-Marvel vs. Capcom 2
-X-Men The Arcade Game (whatever that 4 player beat-em-up was called!)
-Street Fighter 2 CE
-Michael Jackson's Moonwalker (if only for the ending)
-Metal Slug Series
I tried to search for a similar thread but couldn't find one - plus the search is currently borked. Please flame / lock if this is the millionth arcade thread.
