head to head
Resident Evil Revelations asks more than Red Dead Redemption 2, and the gap is optimization.

Execution · Practiced Mastery
A cinematic open-world western leaning on shooting feel and atmosphere.

Optimization · Practiced Mastery
Episodic survival horror aboard a derelict cruise ship, with a loot-driven Raid Mode.
Red Dead Redemption 2 leans Execution (Practiced Mastery); Resident Evil Revelations 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.
Red Dead Redemption 2
Gunplay and Dead Eye reward aim and timing.
Resident Evil Revelations
Aiming under pressure matters in tight corridors
Red Dead Redemption 2 leans a little harder on reads, though the gap is small.
Red Dead Redemption 2
Enemies use scripted AI patterns, not adaptation.
Resident Evil Revelations
Ooze enemies are scripted
Resident Evil Revelations leans a little harder on variance, though the gap is small.
Red Dead Redemption 2
Some hunting and weather randomness, lightly hidden.
Resident Evil Revelations
Scanner pickups and ambushes surprise first run
Resident Evil Revelations leans clearly harder on optimization.
Red Dead Redemption 2
Loadouts and routes solvable but loose.
Resident Evil Revelations
Raid Mode builds and weapon customization 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.
