BIG games are handicapped in rapidly changing industries, markets where surprise moves by new players is a possibility, situations requiring innovative and creative approaches, and in decisions calling for specific practical ideas rather than more generic moves (such as raise, stay or lower prices by x%). Decision makers looking at war gaming should also be minded of game theory’s own lack of empirical support, as people seem to irrationally follow behaviors that do not result in their best outcome. (Chussil, of Advanced Competitive Strategies, argues that "irrational" behaviors can come from the complexity of competitive-strategy problems; it can be extremely difficult to identify behaviors that produce "best" outcomes.) BIB Business war games employing role-playing and competitor analytical techniques are most beneficial in business strategy at the business unit, market, brands, product and project levels. BIB games have been applied with great success to new product launches, offensive and defensive moves against specific competitors (whose response is analyzed using the advanced competitor analysis techniques), in organizational development’s (training the next generation executive cadre) "competitive landscape" games, and in brand revival and new market entry situations. According to participants, BIB games provide touch reality-based challenge to strategies and plans that helps companies cope with uncertainty. They are less useful in conglomerate strategy as they apply to business strategy and not across unrelated industries.

NWG (Pure Role-Play) "Pure Role-Play" Negotiation War Games have shown to generate significantly better predictions of negotiation outcomes compared to other popular methods. "Pure Role-Play" Negotiation War Games have also been shown to ensure significantly lower prices in procurement negotiations, and greater writedowns in auditor vs. client negotiations concerning obsolete inventory. "Pure Role-Play" War Games have been used extensively in business negotiations. "Pure Role-Play" War Games are furthermore often used in politics. Negotiation War Gaming was used to prepare President Ronald Reagan for his negotiations with Gorbachev in Reykevik and Geneva in 1985 and 1986.
