A book/game bundle is a really interesting idea.
Another interesting idea, I think more for Matrix than PG, would be to explore something on the History Channel. Is there a large population of history focused individuals who are mainly passive in terms of historical media who could be enticed into a more interactive relationship with historical media?
I haven't been keeping up with flight sims too much these days, but I think the promise of advancement still remains with the third party individuals working with F4, BOB, and MA. I left RBII3D off that list, although great things have been accomplished, they are ultimately limited as they work without the benefit of source code.
Also, I tend to believe that markets for games like other forms of media entertainment tends to be cyclic. In some ways, it's more like a little ecosystem where a particular niche oscillates between near extinction to a rapid exponential growth/mass starvation/crash.
So, aside from open source modders, perhaps the best positioned entities are small/lean ventures working over long periods of time. Due to low overhead and great focus and passion, they can survive the lean times and they are well positioned to join in the feeding frenzy during the booms.
So, does anyone care to venture a prediction when the next boom for strategic realtime operational wargaming will take place? And what event(s) will trigger it?
I just thought I would inject some philosophical musings into today's conversation.
