Grand Theft Auto V
Driving and shooting demand decent inputs.
Guns, Gore and Cannoli 2
run-and-gun aiming and dodging skill
Grand Theft Auto V leans clearly harder on reads.
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
Guns, Gore and Cannoli 2
scripted enemy waves, not adaptive
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto V
Some mission and lobby randomness.
Guns, Gore and Cannoli 2
some enemy spawn randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto V
Heists, money loops, builds learnable.
Guns, Gore and Cannoli 2
