No.092Stardew Valley01The core loop
Action → feedback → next choice- 01Perform an action
- 02That skill gains experience
- 03Level-up unlocks efficiency
- 04Doing it again feels better
↻Feedback changes the situation — the next round starts from there.
Walk through one round
A simplified design example. Situations and numbers illustrate the mechanic, not exact rules from a reference game.
- T1
Turn 1 · The situation
Fishing level 2, each cast costs 4 energy, 30 XP to level 3, about 8 XP per fish.
- T2
Turn 2 · The player chooses
The player shelves farming and fishes four catches in the afternoon.
- T3
Turn 3 · The feedback
Level 3 reached: casts cost 3 energy and a new bait recipe unlocks.
- T4
Turn 4 · The next decision
The bait speeds future bites, so the player schedules a weekly fishing day.
How it plays
Each skill earns experience only from matching actions, such as chopping wood or casting a line. Levels lower costs, raise yields or unlock recipes, with level-up pings and progress bars telling the player they are getting better.
What the player weighs
- Train weaknesses vs farm strengths: shoring up a weak skill is slow but makes you well-rounded.
- Time spent vs today's goal: grinding a skill may not advance what you actually need done.
02Start small
Scope is an editorial estimate for the minimum prototype, not the reference game or a production schedule.
03One mechanic, different implementations

Stardew Valley
Farming, mining, fishing, foraging and combat each level from their own activities, unlocking crafting recipes and better tool efficiency.

The Elder Scrolls V: Skyrim Special Edition
Skills like One-Handed, Sneak and Smithing rise through use, and those gains drive overall character level and perk points.
The difference worth noticing
Stardew ties growth to a daily production rhythm, while Skyrim funnels skill use straight into character level and combat power.

04What could you combine?
Timed contracts pay a bonus tied to a specific skill, forcing a choice between meeting the deadline with a strong skill or using the job to train a weak one.
