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

Optimization · Pure Optimization
A post-nuclear RPG expanded in scope where tagged builds and Gifted-trait optimization dominate.

Optimization · Pure Optimization
A turn-based tactics game testing positioning and resource planning under hit-chance RNG.
Fallout 2 leans Optimization (Pure Optimization); Rebel Cops leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Fallout 2
Turn-based AP system makes twitch entirely irrelevant
Rebel Cops
Aiming is point-based, not twitch reflex
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Fallout 2
All tribal and Enclave enemies run fixed scripted combat routines
Rebel Cops
Enemy AI is scripted, not adaptive modelling
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Fallout 2
Hidden special encounters and timed events create significant unknown-information space
Rebel Cops
Hit chances and detection add real randomness
Fallout 2 leans a little harder on optimization, though the gap is small.
Fallout 2
SPECIAL and skill tagging with Gifted trait produce well-known dominant build strategies
Rebel Cops
Positioning, resource scarcity and turn planning decide missions
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.
