I know BBH has 1CCed Narc and Total Carnage, and a guy named The Pro has 1CCed Smash TV. I don't know if that means they're not credit feeders though. For instance, in the last stages of all those games, death is an inevitability and you just better hope you've gotten enough extends. That's a credit-feeding design at the very least, even if it is possible to overcome it. I'll say it's a toss up for now if you don't mind.
Do Rampage and the sequel Rampage: World Tour qualify? (IIRC the arcade version of Rampage doesn't end.)
I wouldn't say so. If I recall correctly, both Rampages follow the golden-age concept of "see how long you can play before your health/lives eventually chip away." You could probably play for an hour in those games, whereas in Revolution X you'd be a god if you made it to level 3.
Oh, and I forgot Atari's Batman game. Just look at those projectiles in Flugenheim Museum, and if you dodge them you'll just get stabbed instead.
Macaw knows a bunch of these. Technos and Konami converted some of their games into credit-feeders for the American releases. Makes you wonder why 1CCing is such a foreign idea to some people.
