X4: Foundations asks more than Braid, and the gap is variance.

Optimization · Pure Optimization
A platformer puzzle game built around deducing and exploiting each world's unique time-manipulation rule.

Optimization · Pure Optimization
Open-ended space simulation of trading, station-building and faction warfare.
Braid leans Optimization (Pure Optimization); X4: Foundations leans Optimization (Pure Optimization).
Braid leans a little harder on execution, though the gap is small.
Braid
Precise jumps and time-rewind timing are load-bearing
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.
Braid
No opponent; solo platforming puzzle
X4: Foundations
AI factions follow mappable economic logic.
X4: Foundations leans clearly harder on variance.
Braid
All puzzles are deterministic and hand-crafted
X4: Foundations
Simulated wars create some unpredictability.
X4: Foundations leans a little harder on optimization, though the gap is small.
Braid
Understanding each world's time-manipulation rule and its exact solution is the game
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.
