If you’re Booz Allen Hamilton, its also good for lots of contracts as they are one of the world’s premier war-gaming strategy consulting firms. Not only do they have a pre-eminent business consultancy, they also provide consulting services to many government agencies (including a long-standing relationship with the CIA and US Army) for military strategy and war readiness. Not surprisingly, they sell as one of their core competencies to their corporate clients their ability to develop simulations of competitor behavior and strategy.
It makes a lot of sense. Business is oftentimes compared to war as the elements which make military strategy work — culture, information flow, understanding of competitors, speed, technology, etc. — also make business strategy work.
So, when I’m playing Starcraft, it’s not wasting time, it’s really about training myself strategically!
