head to head
From Space asks more than Grand Theft Auto: San Andreas, and the gap is execution.

Execution · Practiced Mastery
A top-down co-op shooter testing aim and upgrade optimization against alien swarms.

Optimization · Practiced Mastery
A sprawling open-world crime epic with RPG-style character stats across a whole state.
From Space leans Execution (Practiced Mastery); Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery).
From Space leans clearly harder on execution.
From Space
Twin-stick aiming and dodging swarms is core
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
From Space leans a little harder on reads, though the gap is small.
From Space
Aliens are scripted/random, not adaptive minds
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
From Space leans clearly harder on variance.
From Space
Random spawns and drops add chaos
Grand Theft Auto: San Andreas
Territory wars and traffic add light randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
From Space
Weapon upgrades and squad coordination reward planning
Grand Theft Auto: San Andreas
Stats, gym, weapon skill, and routes reward systematic play
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.
