Execution · Practiced Mastery
Crude comedy 3D platformer of boss fights, parodies, and set-piece variety.

Optimization · Practiced Mastery
A sprawling open-world crime epic with RPG-style character stats across a whole state.
Conker's Bad Fur Day leans Execution (Practiced Mastery); Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery).

Bosses and enemies fully scripted
Grand Theft Auto: San Andreas

Grand Theft Auto: San Andreas leans a little harder on variance, though the gap is small.
Conker's Bad Fur Day
Linear, authored content throughout
Grand Theft Auto: San Andreas

Grand Theft Auto: San Andreas leans a little harder on optimization, though the gap is small.
Conker's Bad Fur Day
Context-sensitive solutions are learnable
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.
