head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Optimization · Pure Optimization
A colonial-fantasy RPG won by faction routing and build optimization.

Optimization · Pure Optimization
Optimising tower placement, research and economy against scripted alien waves.
Greedfall leans Optimization (Pure Optimization); Revenge of the Titans 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.
Greedfall
Lock-on action combat, modest demand
Revenge of the Titans
Mid-wave building rewards speed but never twitch-defines outcomes
Greedfall leans a little harder on reads, though the gap is small.
Greedfall
Scripted enemy patterns
Revenge of the Titans
Titan waves follow set paths without adapting
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Greedfall
Loot and check rolls
Revenge of the Titans
Wave compositions are unknown on a first campaign run
Revenge of the Titans leans a little harder on optimization, though the gap is small.
Greedfall
Faction routing, builds, crafting central
Revenge of the Titans
Tech choices, placement and economy are the whole game
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.
