Devil World leans Execution (Practiced Mastery); Red Dead Redemption 2 leans Execution (Practiced Mastery).
Devil World leans clearly harder on execution.
Devil World
Dodging demons while the scrolling maze crushes you is twitch
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.
Devil World
Demons chase on simple fixed logic
Red Dead Redemption 2
Enemies use scripted AI patterns, not adaptation.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Devil World
Scroll direction shifts add mild unpredictability
Red Dead Redemption 2
Some hunting and weather randomness, lightly hidden.
Devil World leans a little harder on optimization, though the gap is small.
Devil World
Maze routes and cross timing are learnable patterns
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.
