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
Engineering unit pairings and reclass paths to dominate maps whose enemy scripts are fully mappable.
Aven Colony leans Optimization (Pure Optimization); Fire Emblem: Awakening leans Optimization (Pure Optimization).
Fire Emblem: Awakening leans a little harder on execution, though the gap is small.
Aven Colony
City management UI has no twitch dimension
Fire Emblem: Awakening
No twitch elements; pair-up placement is the only spatial decision under time
Fire Emblem: Awakening leans a little harder on reads, though the gap is small.
Aven Colony
Alien threats are scripted with no player-modelling behaviour
Fire Emblem: Awakening
Enemies follow simple aggro patterns on fixed maps
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
Fire Emblem: Awakening
Hit and crit rates plus random level-up stats create run variance
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Aven Colony
Colony expansion, air quality chains, and tech routing are the solvable core
Fire Emblem: Awakening
Marriage pairings and Second Seal reclass chains are the optimization spine
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.
