head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

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

Optimization · Pure Optimization
A sprawling space RPG-strategy hybrid where mastering trade, upgrades, and fleet building trumps everything else.
Fallout 2 leans Optimization (Pure Optimization); Space Rangers 2: Dominators 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
Space Rangers 2: Dominators
real-time combat pauses, minimal twitch skill needed
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
Space Rangers 2: Dominators
no adaptive human opponent in single-player sandbox
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
Space Rangers 2: Dominators
random encounters, text quests, galaxy generation
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
Space Rangers 2: Dominators
deep economy, tech tree, fleet build all solvable
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.
