head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

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

Optimization · Practiced Mastery
A physics platformer testing creative slicing solutions and traversal over cut terrain.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); Tiny and Big: Grandpa's Leftovers leans Optimization (Practiced Mastery).
Tiny and Big: Grandpa's Leftovers leans a little harder on execution, though the gap is small.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Tiny and Big: Grandpa's Leftovers
Aiming cuts and platforming on tumbling slabs takes coordination
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
Tiny and Big: Grandpa's Leftovers
No adaptive opponent anywhere
Grand Theft Auto: San Andreas leans a little harder on variance, though the gap is small.
Grand Theft Auto: San Andreas
Territory wars and traffic add light randomness
Tiny and Big: Grandpa's Leftovers
Physics wobble slightly but levels are fixed
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto: San Andreas
Stats, gym, weapon skill, and routes reward systematic play
Tiny and Big: Grandpa's Leftovers
Figuring out which rock to slice where is the puzzle
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.
