head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, 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
Minimalist transit puzzle; route topology under spawning pressure.
Aven Colony leans Optimization (Pure Optimization); Mini Metro leans Optimization (Pure Optimization).
Mini Metro leans a little harder on execution, though the gap is small.
Aven Colony
City management UI has no twitch dimension
Mini Metro
light real-time line-drawing
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
Mini Metro
no adversary
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Aven Colony
Landing site resources and alien attack timing carry moderate RNG
Mini Metro
station spawn pattern
Mini Metro 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
Mini Metro
line topology and 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.
