head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.

Execution · Practiced Mastery
A slow horror-leaning Doom reboot built on darkness and scripted ambushes.

Optimization · Practiced Mastery
Co-op survival testing resource discipline and routes under randomised item spawns.
Doom 3 leans Execution (Practiced Mastery); No More Room in Hell leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Doom 3
Closet ambushes punish slow target acquisition
No More Room in Hell
Scarce-ammo headshots and melee spacing under pressure
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Doom 3
Demon spawns are scripted triggers, not adaptation
No More Room in Hell
Zombies shamble on scripts without modelling players
No More Room in Hell leans a little harder on variance, though the gap is small.
Doom 3
Darkness hides ambushes until memorised
No More Room in Hell
Dynamic objectives and random item spawns reshuffle each run
No More Room in Hell leans a little harder on optimization, though the gap is small.
Doom 3
Ammo management and trigger knowledge trivialise replays
No More Room in Hell
Route knowledge, resource discipline and teamwork are the real edge
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.
