head to head
Eastside Hockey Manager asks more than Oxygen Not Included, and the gap is reads.

Optimization · Pure Optimization
A text-based hockey management game testing long-term roster building and development optimization.

Optimization · Pure Optimization
Engineering precise gas, liquid, and power circuits to keep a subterranean colony alive indefinitely.
Eastside Hockey Manager leans Optimization (Pure Optimization); Oxygen Not Included leans Optimization (Pure Optimization).
Oxygen Not Included leans a little harder on execution, though the gap is small.
Eastside Hockey Manager
No physical inputs; all text-based management
Oxygen Not Included
All inputs are build-order clicks; no twitch required
Eastside Hockey Manager leans clearly harder on reads.
Eastside Hockey Manager
AI managers have mild tendencies but are largely modelable
Oxygen Not Included
No adversary of any kind exists in the colony
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Eastside Hockey Manager
Sim results, injuries, and development rolls create meaningful variance
Oxygen Not Included
Asteroid seed and geyser placement carry meaningful but bounded randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Eastside Hockey Manager
Scouting, line management, and trade strategy are deeply solvable
Oxygen Not Included
Gas, liquid, and power engineering are essentially a solvable engineering puzzle
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.
