Aero Fighters 3
Dodging dense bullet patterns is the whole challenge
Red Dead Redemption 2
Gunplay and Dead Eye reward aim and timing.

Aero Fighters 3
Enemy waves are fully scripted, nothing adapts
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.
Aero Fighters 3
Minor item drops aside, patterns are fixed once learned
Red Dead Redemption 2
Some hunting and weather randomness, lightly hidden.
Aero Fighters 3 leans clearly harder on optimization.
Aero Fighters 3
Memorising spawns, routes and ship choice drives high scores
Red Dead Redemption 2
Loadouts and routes solvable but loose.
