The run-level economy that makes gold, keys, health, and timing argue with each other.
A shop economy is the temporary market structure inside a run. Strong shops force players to weigh immediate survival against long-term build potential.
Example
Spelunky shops tempt players with bombs, weapons, and mobility tools. Slay the Spire shops compete with card removal, relics, potions, and future campfire needs.
Why it matters
Shop economies matter because they create planning without slowing the game into a full management sim.
