Watch a video of Galloping Ghost Arcade and you'll really freak out! But please keep an open mind.
They have about 400 games but I would say that about 150 games are in their original cabinets (nice overall total number, right?). The owner is a great guy but is younger and focused on the newer generation of fighting games that didn't really have an original cabinet. In terms of pure numbers, you would see they have many classic games in original cabinets (e.g., Gyruss, Frogger,
, Robotron, Berzerk, Frenzy, Burgertime, Warlords, Defender, Spy Hunter, Tapper, Tron, Discs of Tron, Centipede, Millipede, etc. etc.) whereas they have some questionable conversions of other classic games (e.g.,
Jr., Pengo, Track & Field, Dragon's Lair, Moon Patrol).
The main point is that in pure whole numbers, they have a ton of games in their original cabs but have also made a point of providing at least a workable version of many classic games in conversion cabinets. They are keeping many games alive even though they aren't able to secure original cabs for all of them.
With respect to the fighting games, I couldn't care less about them but it appears that the culture of these games is that they did not have original cabs associated with them but the players were just seeking good controls to play the games. Maybe I am wrong.
