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
Engineering unit pairings and reclass paths to dominate maps whose enemy scripts are fully mappable.
Fallout 2 leans Optimization (Pure Optimization); Fire Emblem: Awakening 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
Fire Emblem: Awakening
No twitch elements; pair-up placement is the only spatial decision under time
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
Fire Emblem: Awakening
Enemies follow simple aggro patterns on fixed maps
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
Fire Emblem: Awakening
Hit and crit rates plus random level-up stats create run variance
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
Fire Emblem: Awakening
Marriage pairings and Second Seal reclass chains are the optimization spine
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.
