head to head
Rage asks more than Mafia III, and the gap is execution.

Optimization · Practiced Mastery
Revenge-driven open-worlder dismantling a sixties crime empire district by district.

Execution · Practiced Mastery
id Software's post-apocalyptic shooter mixing crisp gunplay with buggy racing.
Mafia III leans Optimization (Practiced Mastery); Rage leans Execution (Practiced Mastery).
Rage leans clearly harder on execution.
Mafia III
Stealth takedowns and gunfights
Rage
id-style gunplay precision against agile bandits.
Rage leans a little harder on reads, though the gap is small.
Mafia III
Racket guards follow fixed AI
Rage
Enemy mobility is scripted animation, not adaptation.
Rage leans a little harder on variance, though the gap is small.
Mafia III
Open world is static
Rage
First-run unknowns in dungeons and loot.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Mafia III
District takeover loop and underboss assignments
Rage
Crafting, ammo economy, and wingstick usage reward planning.
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
