What kind of gameplay and structure would be the best fit?
I actually think this would be the way for Tekken brawler-style gameplay ( as seen in the PS2 game Urban Reign below) to make a strong return.
The heightened nature of the movie resonated with many because of the earnestness and heart of the lead protagonists' portrayals, and having that story as the basis of the game would fit well with simultaneously absurd yet brutal and relatively grounded combat of Urban Reign:
It is not merely the characters' actions themselves that made RRR amazing, but also the effects of those moves/attacks, and having an over-the-top, yet consistent series of enemy hit reactions and physics would go a long way in helping the game capture the essence of the film.
There would also need to be co-op, horse and motorcycle gameplay, and unlockable lore of the revolutionaries portrayed on the movie.
