head to head
Neither is simply harder - they are hard in different places. Cardania: Epoch Wars demands more reads; Fallout: New Vegas demands more execution.

Optimization · Pure Optimization
A persistent multiplayer 4X testing map-control strategy against other human players.

Optimization · Pure Optimization
A faction-driven RPG-shooter where build and route planning shape every ending.
Cardania: Epoch Wars leans Optimization (Pure Optimization); Fallout: New Vegas leans Optimization (Pure Optimization).
Fallout: New Vegas leans clearly harder on execution.
Cardania: Epoch Wars
Strategy clicks, no twitch dimension
Fallout: New Vegas
Shooter inputs with VATS assist
Cardania: Epoch Wars leans clearly harder on reads.
Cardania: Epoch Wars
Live human rivals contesting the map can be predicted
Fallout: New Vegas
Scripted factions and enemies
Cardania: Epoch Wars leans clearly harder on variance.
Cardania: Epoch Wars
Anomalies and shifting maps add hidden information
Fallout: New Vegas
Some loot and crit RNG
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Cardania: Epoch Wars
Resource control and faction strategy dominate the metagame
Fallout: New Vegas
Faction routing, perks, builds heavily rewarded
