1. A game for one or more players, where said game is based on the simulation of a value of a specific high-value asset (HVA) selected from a plurality of HVAs, said game comprising: a processor; and a memory device storing a plurality of instructions, which when executed by said processor, causes said processor to determine the value of the specific HVA with a valuation model based on the value of HVAs including HVAs other than the specific HVA; accept a guess of the value from a first player of said one or more players; calculate a score corresponding to the deviation of said guess from the value; and store prior play information related to specific previous plays of said game, where said prior play information includes a player identification, the HVA, and two or more of the value, guess, or score, and where said valuation model provides the value of the specific HVA that depends on said prior play information, where said plurality of instructions, which when executed by said processor, causes said processor to determine the value of the specific HVA with said valuation model by having said processor; establish a first subset of HVAs having a proximity to the specific HVA; identify a first set of individual plays having the HVA within said first subset of HVAs; determine an authority for each player identified in said first set of individual plays; identify a second set of individual plays having the HVA identical with the specific HVA; and determine the value of the specific HVA from a weighted average from said guesses of said second set of individual plays and said authority corresponding to the player of said individual plays.
