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
Combat-focused Infinity Engine RPG built on D&D party optimization.
Aven Colony leans Optimization (Pure Optimization); Icewind Dale 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
Icewind Dale
Pausable real-time needs little dexterity
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
Icewind Dale
Enemies follow fixed AI scripts
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
Icewind Dale
D&D dice rolls and random loot tables
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
Icewind Dale
Party builds, spell prep, and encounter knowledge
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.
