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

Optimization · Pure Optimization
Fantasy 4X with strong asymmetric factions and quest paths.

Optimization · Pure Optimization
A timer-and-spreadsheet 4X where officer math and resource pipelines decide everything.
Endless Legend leans Optimization (Pure Optimization); Star Trek Fleet Command 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.
Endless Legend
turn-based
Star Trek Fleet Command
Menu taps and timers - no hands required
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Endless Legend
scripted AI, limited MP
Star Trek Fleet Command
Rival alliances raid and retaliate, mildly worth predicting
Endless Legend leans a little harder on variance, though the gap is small.
Endless Legend
quest and tech rolls
Star Trek Fleet Command
Loot rolls and unscouted systems add hidden information
Endless Legend leans a little harder on optimization, though the gap is small.
Endless Legend
faction-specific yield optimization
Star Trek Fleet Command
Officer synergies, ship tiers and resource pipelines are the real 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.
