head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, 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 grand tactical RPG where deep class and alignment optimization against scripted enemy formations defines mastery.
Fallout 2 leans Optimization (Pure Optimization); Ogre Battle 64 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
Ogre Battle 64
Real-time unit marching is automatic; player input minimal
Fallout 2 leans a little harder on reads, though the gap is small.
Fallout 2
All tribal and Enclave enemies run fixed scripted combat routines
Ogre Battle 64
Enemy leaders scripted; no adaptive AI
Fallout 2 leans a little harder on variance, though the gap is small.
Fallout 2
Hidden special encounters and timed events create significant unknown-information space
Ogre Battle 64
Unit encounter randomness and morale swings add moderate variance
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Fallout 2
SPECIAL and skill tagging with Gifted trait produce well-known dominant build strategies
Ogre Battle 64
Unit class configuration, formation, and alignment routing are the dominant system
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.
