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

Execution · Practiced Mastery
Strategic dismemberment under resource pressure, solved by upgrade planning and practiced limb-aiming.

Execution · Practiced Mastery
Methodical infiltration planning paid off by one well-compensated rifle shot.
Dead Space (2008) leans Execution (Practiced Mastery); Sniper Elite: Resistance leans Execution (Practiced Mastery).
Dead Space (2008) leans a little harder on execution, though the gap is small.
Dead Space (2008)
Precise limb-targeting under Necromorph pressure is the core skill
Sniper Elite: Resistance
Ballistics-compensated shots and stealth timing need steady hands
Sniper Elite: Resistance leans a little harder on reads, though the gap is small.
Dead Space (2008)
Necromorphs follow fixed approach patterns, not player modelling
Sniper Elite: Resistance
Invasion mode adds occasional human cat-and-mouse
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dead Space (2008)
Store stock is deterministic; minor drop variance on kills
Sniper Elite: Resistance
Patrol details are scripted-but-unknown on first infiltration
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Dead Space (2008)
Weapon upgrading, power-node routing and stasis timing are optimisable
Sniper Elite: Resistance
Route planning, sound masking and shot setups reward study
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.
