head to head
Kingdoms of Amalur: Reckoning asks more than Red Dead Redemption 2, and the gap is optimization.

Optimization · Practiced Mastery
A loot-heavy open-world action RPG with flashy combo combat and a famously breakable crafting system.

Execution · Practiced Mastery
A cinematic open-world western leaning on shooting feel and atmosphere.
Kingdoms of Amalur: Reckoning leans Optimization (Practiced Mastery); Red Dead Redemption 2 leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Kingdoms of Amalur: Reckoning
Dodge-and-combo combat, forgiving timing
Red Dead Redemption 2
Gunplay and Dead Eye reward aim and timing.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Kingdoms of Amalur: Reckoning
Enemies never adapt to your habits
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.
Kingdoms of Amalur: Reckoning
Loot rolls add light randomness
Red Dead Redemption 2
Some hunting and weather randomness, lightly hidden.
Kingdoms of Amalur: Reckoning leans clearly harder on optimization.
Kingdoms of Amalur: Reckoning
Destiny builds and crafting trivialise difficulty
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.
