head to head
Grand Theft Auto: San Andreas asks more than Sonic Frontiers, and the gap is optimization.

Optimization · Practiced Mastery
A sprawling open-world crime epic with RPG-style character stats across a whole state.

Execution · Practiced Mastery
An open-zone Sonic experiment with cyberspace stages.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); Sonic Frontiers leans Execution (Practiced Mastery).
Sonic Frontiers leans a little harder on execution, though the gap is small.

Sonic Frontiers

Grand Theft Auto: San Andreas
Stats, gym, weapon skill, and routes reward systematic play

Skill tree and stat farming
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.
