Price always matters because rational consumers always consider value. The classic economic construct defines prefrence curves, e.g., guns vs. butter or perhaps more generally, guns vs. all other things (Charles McCloskey, U of Iowa dept. economics). If a collector pays a premium price for a game, it is because he/ she values it at that price point. To assume otherwise is to believe buyers ars making irrational decisions which seems, frankly, rather condescending by the observer making that assumption.
