head to head
Astral Chain asks more than Grand Theft Auto V, and the gap is execution.

Execution · Practiced Mastery
A Platinum action game about juggling two characters at once with style.

Execution · Practiced Mastery
Sandbox crime playground spanning shooting, driving, and a persistent online economy.
Astral Chain leans Execution (Practiced Mastery); Grand Theft Auto V leans Execution (Practiced Mastery).
Astral Chain leans clearly harder on execution.
Astral Chain
Dual character-Legion control demands real dexterity.
Grand Theft Auto V
Driving and shooting demand decent inputs.
Grand Theft Auto V leans a little harder on reads, though the gap is small.
Astral Chain
Enemy patterns scripted, not adaptive.
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
Grand Theft Auto V leans a little harder on variance, though the gap is small.
Astral Chain
Encounters fixed and replayable.
Grand Theft Auto V
Some mission and lobby randomness.
Astral Chain leans a little harder on optimization, though the gap is small.
Astral Chain
Legion abilities and combo scoring learnable.
Grand Theft Auto V
Heists, money loops, builds learnable.
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.
