head to head
Neither is simply harder - they are hard in different places. Fallout: New Vegas demands more execution; Panzer General demands more variance.

Optimization · Pure Optimization
A faction-driven RPG-shooter where build and route planning shape every ending.

Optimization · Pure Optimization
Classic turn-based operational wargame about blitzing across WWII campaign maps with a carryover core army.
Fallout: New Vegas leans Optimization (Pure Optimization); Panzer General leans Optimization (Pure Optimization).
Fallout: New Vegas leans clearly harder on execution.
Fallout: New Vegas
Shooter inputs with VATS assist
Panzer General
Turn-based hex moves; no physical demands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Fallout: New Vegas
Scripted factions and enemies
Panzer General
Scripted AI opponent; no adaptive modeling
Panzer General leans clearly harder on variance.
Fallout: New Vegas
Some loot and crit RNG
Panzer General
Combat dice rolls and hidden enemy deployments
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Fallout: New Vegas
Faction routing, perks, builds heavily rewarded
Panzer General
Prestige economy, unit upgrades, optimal advance routing dominate
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.
