Buy super ghost and goblins for a dollar or spend 10 bucks in tokens on it?
Yeah kinda weird ass concept
Not really, Xbox Game Room had a similiar set-up: You could either buy the games for 3/5 dollars, of pay for a virtual quater, and play it limitedly.
Gave the option to replicate a real arcade experience, and maybe get a larger amount of play for, say, 2 dollars across multiple games, than some people would ever think to actually spend with arcade classics.
Also, you could "challenge" people to score runs and stuff per game, so being able to accept a friendly challenge, for 25 cents, VS having to fully pay for a game you didn't own, was a nice option.
Gameroom also changed over time, though; from a "Buy a single Xbox License / pc / both!" structure (with different cost for 1 or multi license), to later becoming a flat, cheaper price for both.
I wonder if Capcom has any dreams in this regard? Very unlikely in some ways, but if they allowed a purchase in this arcade to apply to all interconnected devices (such as all SEN / PSN purchases would work on Vita, and PS3, maybe even mobile, and all XBLA purchases worked on Surface, XBLA, Windows Phone, and Windows 8), that'd be a pretty nice way for things to work out...
