Auction appraisal strategy
Curio
Inspect unusual objects, estimate their value, and compete through calculated auction decisions.

The idea behind the game
A deterministic auction and appraisal strategy game centered on evidence, inspection, valuation, rival behavior, and long-term collecting decisions.
Each run asks the player to decide what an object is worth before certainty is available. Inspection evidence, valuation ranges, rival behavior, and bidding create the tension; deterministic seeds keep those decisions reproducible enough for balancing and comparison.
