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
Expanding a self-sufficient alien colony by solving atmosphere, power, and resource chains under scripted threats.

Optimization · Pure Optimization
Dystopian management adventure about a landlord spying on tenants for a totalitarian state.
Aven Colony leans Optimization (Pure Optimization); Beholder 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.
Aven Colony
City management UI has no twitch dimension
Beholder
Simple point-and-click landlord actions
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Aven Colony
Alien threats are scripted with no player-modelling behaviour
Beholder
Tenants follow scripted schedules, not adaptive
Aven Colony leans a little harder on variance, though the gap is small.
Aven Colony
Landing site resources and alien attack timing carry moderate RNG
Beholder
Tenant events and directives surprise first runs
Aven Colony leans a little harder on optimization, though the gap is small.
Aven Colony
Colony expansion, air quality chains, and tech routing are the solvable core
Beholder
Money, time, and blackmail decision routing
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.
