head to head
Sniper Elite V2 asks more than Grand Theft Auto: San Andreas, and the gap is execution.

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

Execution · Practiced Mastery
Patient ballistic aiming wrapped in plannable stealth positioning.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); Sniper Elite V2 leans Execution (Practiced Mastery).
Sniper Elite V2 leans clearly harder on execution.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Sniper Elite V2
Ballistics-compensated long shots demand steady precise aim
Sniper Elite V2 leans a little harder on reads, though the gap is small.
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
Sniper Elite V2
Enemy AI runs fixed alert routines
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto: San Andreas
Territory wars and traffic add light randomness
Sniper Elite V2
Wind and patrol details vary slightly per attempt
Grand Theft Auto: San Andreas leans a little harder on optimization, though the gap is small.
Grand Theft Auto: San Andreas
Stats, gym, weapon skill, and routes reward systematic play
Sniper Elite V2
Positioning, sound masking and route planning are learnable
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.
