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
Tests isometric jump precision and room-by-room spatial puzzle reading.

Execution · Practiced Mastery
A cinematic open-world western leaning on shooting feel and atmosphere.
Lumo leans Execution (Practiced Mastery); Red Dead Redemption 2 leans Execution (Practiced Mastery).
Lumo leans a little harder on execution, though the gap is small.
Lumo
Isometric jumps with tricky perspective punish imprecision
Red Dead Redemption 2
Gunplay and Dead Eye reward aim and timing.
Red Dead Redemption 2 leans a little harder on reads, though the gap is small.
Lumo
Rooms are fixed challenges with no opponent
Red Dead Redemption 2
Enemies use scripted AI patterns, not adaptation.
Red Dead Redemption 2 leans a little harder on variance, though the gap is small.
Lumo
Secrets hide only until the room is studied
Red Dead Redemption 2
Some hunting and weather randomness, lightly hidden.
Lumo leans a little harder on optimization, though the gap is small.
Lumo
Each chamber is a solvable spatial puzzle
Red Dead Redemption 2
Loadouts and routes solvable but loose.
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.
