Optimization · Pure Optimization
Farm scheduling and economy optimisation across seasons and relationships.

Optimization · Pure Optimization
An open-world RPG mostly about discovering and stacking exploitable progression systems.
Harvest Moon DS leans Optimization (Pure Optimization); The Elder Scrolls V: Skyrim leans Optimization (Pure Optimization).
The Elder Scrolls V: Skyrim leans clearly harder on execution.
Harvest Moon DS
Daily chores have no twitch component
The Elder Scrolls V: Skyrim
Combat is forgiving; aim and timing rarely punish you.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Harvest Moon DS
Villagers run fixed schedules, never adapt
The Elder Scrolls V: Skyrim
Enemy AI is scripted and exploitable; not adaptive.
Harvest Moon DS leans a little harder on variance, though the gap is small.
Harvest Moon DS
Weather, festivals and sprite unlocks hide some information
The Elder Scrolls V: Skyrim
Loot tables and leveled lists inject mild randomness.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Harvest Moon DS
Crop rotations, scheduling and money loops are the whole game
The Elder Scrolls V: Skyrim
Skill stacking, enchant loops, and exploits are deeply solvable.
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.
