head to head
Grand Theft Auto: San Andreas asks more than Clive Barker's Jericho, and the gap is optimization.

Execution · Practiced Mastery
Corridor shooting plus picking the right squad ability for each scripted encounter.

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

Clive Barker's Jericho
Aim and squad-ability timing through corridor firefights
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.
Clive Barker's Jericho
Horrors attack on fixed scripts, nothing adapts
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
Grand Theft Auto: San Andreas leans a little harder on variance, though the gap is small.
Clive Barker's Jericho
Linear set pieces with minimal randomness
Grand Theft Auto: San Andreas
Territory wars and traffic add light randomness
Grand Theft Auto: San Andreas leans clearly harder on optimization.
Clive Barker's Jericho
Choosing the right squad member per encounter is the layer
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.
