There was a fan campaign asking the director of Tekken 8 to add it as a stage. After being explained why Waffle House is such a good location, he said it'd be difficult to get the rights to use their image for the game.

Over here that would be gas stations, and the fighters are middle aged guys with a beer belly

A whole fighting game of regular people fighting at regular street locations might be pretty good. We could call it Street Fighter... no, wait

Mugen devs, get on this.

Also, it'd be cooler as a beat-'em-up than a fighter.

At Waffle House, if the staff see you fighting in the parking lot, they come out and yell at you to “take it inside”.

Inside would be even better. You could throw plates, squirt syrup bottles, and if you get too close to the customers/staff they could grab/trip you
