Red Dead Redemption 2
Gunplay and Dead Eye reward aim and timing.
Resistance: Fall of Man
Aim and weapon handling against Chimera hordes.
Resistance: Fall of Man leans clearly harder on reads.
Red Dead Redemption 2
Enemies use scripted AI patterns, not adaptation.
Resistance: Fall of Man
Sizable competitive multiplayer added genuine human opposition.
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
Some hunting and weather randomness, lightly hidden.
Resistance: Fall of Man
Campaign unknowns on first pass.
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.
Resistance: Fall of Man
