head to head
Castle Crashers asks more than Red Dead Redemption 2, and the gap is reads.

Castle Crashers leans Execution (Practiced Mastery); Red Dead Redemption 2 leans Execution (Practiced Mastery).
Castle Crashers leans a little harder on execution, though the gap is small.
Castle Crashers
Combo execution and crowd-control timing are the performance ceiling
Red Dead Redemption 2
Gunplay and Dead Eye reward aim and timing.
Castle Crashers leans clearly harder on reads.
Castle Crashers
PvP arenas add light human-opponent reads
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.
Castle Crashers
Enemy spawns follow scripted patterns with minimal randomness
Red Dead Redemption 2
Some hunting and weather randomness, lightly hidden.
Castle Crashers leans a little harder on optimization, though the gap is small.
Castle Crashers
Levelling investment, magic loadout, and pet choice are optimisable
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.
