head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Practiced Mastery
Vehicular mayhem testing car handling plus knowing when wrecking beats racing.

Execution · Practiced Mastery
id Software's post-apocalyptic shooter mixing crisp gunplay with buggy racing.
Carmageddon II: Carpocalypse Now leans Execution (Practiced Mastery); Rage leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Carmageddon II: Carpocalypse Now
Perfect car control trivialises wrecking AI opponents and surviving
Rage
id-style gunplay precision against agile bandits.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Carmageddon II: Carpocalypse Now
AI drivers follow set behaviours, never modelling the player
Rage
Enemy mobility is scripted animation, not adaptation.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Carmageddon II: Carpocalypse Now
Pickup spawns and physics chaos add modest run-to-run noise
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.
Carmageddon II: Carpocalypse Now
Choosing wreck-versus-race strategy and upgrade economy is solvable
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.
