head to head
Fallout: New Vegas asks more than Stronghold, and the gap is execution.

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

Optimization · Pure Optimization
A castle-building strategy game where economic optimization and defense planning is the whole test.
Fallout: New Vegas leans Optimization (Pure Optimization); Stronghold leans Optimization (Pure Optimization).
Fallout: New Vegas leans clearly harder on execution.
Fallout: New Vegas
Shooter inputs with VATS assist
Stronghold
minimal, mostly clicking and management
Stronghold leans a little harder on reads, though the gap is small.
Fallout: New Vegas
Scripted factions and enemies
Stronghold
AI opponents are scripted, minor prediction
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Fallout: New Vegas
Some loot and crit RNG
Stronghold
minor resource and raid randomness
Stronghold leans a little harder on optimization, though the gap is small.
Fallout: New Vegas
Faction routing, perks, builds heavily rewarded
Stronghold
economy and castle-building near-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.
