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
A cinematic open-world western leaning on shooting feel and atmosphere.

Execution · Practiced Mastery
Kiting scripted alien swarms with top-down aim and upgrade planning.
Red Dead Redemption 2 leans Execution (Practiced Mastery); Shadowgrounds Survivor leans Execution (Practiced Mastery).
Shadowgrounds Survivor leans a little harder on execution, though the gap is small.
Red Dead Redemption 2
Gunplay and Dead Eye reward aim and timing.
Shadowgrounds Survivor
Kiting alien swarms with top-down aim is the core demand
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.
Shadowgrounds Survivor
Aliens charge on simple scripted aggression
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Red Dead Redemption 2
Some hunting and weather randomness, lightly hidden.
Shadowgrounds Survivor
Spawn waves vary slightly in survival mode
Shadowgrounds Survivor leans a little harder on optimization, though the gap is small.
Red Dead Redemption 2
Loadouts and routes solvable but loose.
Shadowgrounds Survivor
Weapon upgrade order and positioning 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.
