Let me expound: * The most common result is a glut of barbarians that either kill your soldier or make him an elite. This function is just as well or better served by barbarian camps. * Free techs are the most damaging result. It completely nullifies the early advantage of scientific civs and can result in a skewered game as well as not teaching players the skills of proper research, trading and bullying other civs for techs. * The rarest occurence is a settler. If this happens, it offsets the advantages of agricultural or industrious civs which are the true expansionist civs due to their higher productivity which if properly utilised translates into early expansion. * Gold is very nice but is better obtained by razing barbarian camps. Also, to a lesser degree it offsets the advantage of commercial civs. * Maps are imo the only worthwhile and non-detrimental contribution from Goody Huts albeit those civs with fast-moving scouts may have something to say about that. Therefore, in my opinion, Goody Huts are detrimental. Without them, it would be a better game.
