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

Optimization · Practiced Mastery

The Witcher 2: Assassins of Kings
Tight dodge and parry windows
The Witcher 2: Assassins of Kings leans a little harder on reads, though the gap is small.
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
The Witcher 2: Assassins of Kings
Scripted enemy patterns
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
