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
The classic AD&D CRPG where party planning beats dice luck over time.

Optimization · Systems & Chaos
A roguelike tower-defense hybrid about escorting a crystal through a randomised dungeon.
Baldur's Gate leans Optimization (Pure Optimization); Dungeon of the Endless leans Optimization (Systems & Chaos).
Baldur's Gate leans a little harder on execution, though the gap is small.
Baldur's Gate
Pause-and-play needs minimal dexterity.
Dungeon of the Endless
Pause-friendly control, no twitch demands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Baldur's Gate
Scripted encounters, no adaptation.
Dungeon of the Endless
Monster waves spawn by fixed door-opening rules
Dungeon of the Endless leans a little harder on variance, though the gap is small.
Baldur's Gate
AD&D dice rolls throughout.
Dungeon of the Endless
Unknown rooms and random hero or item finds
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Baldur's Gate
Party builds and encounter prep solvable.
Dungeon of the Endless
Dust economy and turret placement are the real game
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.
