head to head
Cannon Fodder 2 asks more than Grand Theft Auto: San Andreas, and the gap is execution.

Execution · Practiced Mastery
Guiding fragile squads with precise targeting and memorised mission routes.

Optimization · Practiced Mastery
A sprawling open-world crime epic with RPG-style character stats across a whole state.
Cannon Fodder 2 leans Execution (Practiced Mastery); Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery).
Cannon Fodder 2 leans clearly harder on execution.
Cannon Fodder 2
Precise mouse targeting under fire keeps fragile troops alive
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Cannon Fodder 2
Enemy soldiers spawn and charge on scripts
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
Cannon Fodder 2 leans a little harder on variance, though the gap is small.
Cannon Fodder 2
Hazard placements are unknown until a costly first attempt
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.
Cannon Fodder 2
Route order and grenade economy per mission 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.
