first off, I'd put in pinball machines
Medieval Madness
Addams Family
Attack from Mars
and the last Elvira machine from Bally Williams.
Then I'd have the following games:
Radiant Silvergun
Samurai Shodown II
Asura Zanmaden
Metal Slug 3
Blazing Star
19XX
This one puzzle game from Fabtek/Seibu called battle balls or some shit
Super Puzzle Gem Fighter
Vampire Savior
Super Street Fighter II X
Street Fighter Alpha 3
And Street Fighter 2 Rainbow edition (with the multiple fireballs on screen)
This would basically be my own kick ass arcade. Cost would be roughly $15 K for all the pinball machines and 12 x $500 + freight shipping for the candy cabs (no american style cabs because they suck for small children), and $1200 + shipping for all the pcbs I'd need.
I'd want to place it in a local downtown area where there are a lot of young people, and young adults. Not on a college campus, though that's good too, but maybe next to or on the loft part of a coffee house. Rent would probably be a grand, with utilities. And I wouldn't make a dime off it.
