Minsgon Simulator puts a sale price on the creature you have cared for

Minsgon Simulator gives care a commercial consequence. The developer’s description says petting, feeding and cleaning creatures makes them happier and raises the prices they sell for. A better-cared-for creature becomes more valuable stock, which is also the moment you may prefer to keep it.

Training adds another investment. Tamed Minsgons gain experience on training stands and can evolve, increasing both power and value. Eggs produce creatures with differing species, rarity and temperament, so the collection is presented as a set of individuals rather than identical units moving through a shelf. The source does not supply the care thresholds, training times or price formula.

At the sales stand, you choose a price and wait for a customer willing to buy. Keeping a creature is also explicitly supported. A ticketed garden exhibit offers another advertised business activity, although the description does not establish how a particular retained Minsgon affects admissions. That leaves a clear collection question without inventing an optimal business strategy: when care has made this creature worth more, is the higher price a reason to sell it or another reason to hold on?
