Building comparison
head to head
Oxygen Not IncludedvsWarhammer 40,000: Rogue Trader
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.
Oxygen Not Included
Optimization · Pure Optimization
Engineering precise gas, liquid, and power circuits to keep a subterranean colony alive indefinitely.
Warhammer 40,000: Rogue Trader
Optimization · Pure Optimization
A 40K turn-based RPG where conviction stacking and ability chaining produce dominant optimization floors.
Oxygen Not Included leans Optimization (Pure Optimization); Warhammer 40,000: Rogue Trader leans Optimization (Pure Optimization).

Axis by axis
Execution1 vs 2
Warhammer 40,000: Rogue Trader leans a little harder on execution, though the gap is small.
Oxygen Not Included
All inputs are build-order clicks; no twitch required
Warhammer 40,000: Rogue Trader
Turn-based grid combat removes all real-time pressure
Reads0 vs 1
Warhammer 40,000: Rogue Trader leans a little harder on reads, though the gap is small.
Oxygen Not Included
No adversary of any kind exists in the colony
Warhammer 40,000: Rogue Trader
Xenos and heretics run fixed scripted AI routines without modelling players
Variance5 vs 5
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Oxygen Not Included
Asteroid seed and geyser placement carry meaningful but bounded randomness
Warhammer 40,000: Rogue Trader
Hidden voidship encounter outcomes and momentum RNG create unknowns
Optimization10 vs 10
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Oxygen Not Included
Gas, liquid, and power engineering are essentially a solvable engineering puzzle
Warhammer 40,000: Rogue Trader
Arch-Militant conviction stacking and navigator ability chains reach broken optimization ceilings
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.
