head to head
Red Dead Redemption 2 asks more than Sludge Life, and the gap is execution.

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

Optimization · Practiced Mastery
A low-stakes exploration stroll testing curiosity more than any skill axis.
Red Dead Redemption 2 leans Execution (Practiced Mastery); Sludge Life leans Optimization (Practiced Mastery).
Red Dead Redemption 2 leans clearly harder on execution.
Red Dead Redemption 2
Gunplay and Dead Eye reward aim and timing.
Sludge Life

Red Dead Redemption 2 leans a little harder on reads, though the gap is small.
Red Dead Redemption 2

Sludge Life
No opponents at all
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

Sludge Life
Island secrets are scripted-but-unknown until found
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Red Dead Redemption 2
Loadouts and routes solvable but loose.
Sludge Life
Finding tag spots and traversal routes is the loose goal
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.
