X4: Foundations asks more than Gothic II, and the gap is optimization.

Sequel RPG where scarce learning points make build planning brutally consequential.

Optimization · Pure Optimization
Open-ended space simulation of trading, station-building and faction warfare.
Gothic II leans Optimization (Pure Optimization); X4: Foundations leans Optimization (Pure Optimization).
Gothic II leans a little harder on execution, though the gap is small.
Gothic II
Directional melee timing against tough fauna
X4: Foundations
Flying your own ship matters early, fleets later.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Gothic II
No adaptive opposition
X4: Foundations
AI factions follow mappable economic logic.
Gothic II leans a little harder on variance, though the gap is small.
Gothic II
First-run surprises until the island is mapped
X4: Foundations
Simulated wars create some unpredictability.
X4: Foundations leans clearly harder on optimization.
Gothic II
Strict learning-point economy rewards ruthless planning
X4: Foundations
Station logistics and empire economics are a pure engine problem.
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.
