I while back I was wondering how many role players are out there so I asked at a couple forums and the answer was invariably "It's impossible to know." While there may be some truth to that, I finally got a hard number. WOTC did some marketing research a while back and came up with the number 6 million. That number could be more or less at this point, but it gives an idea of how large the pool is.
What does this do for us? Why does it matter? Well it gives us an idea of how large the field is. If there are only 100 thousand gamers, then the market is extremely small and it would seem like all GMs out there have their own blog and probably their own game they're working on. (Ok maybe there aren't 20,000 games out there but it seems that way.) With 6 million, thats about 1-2 million gaming groups out there you can get your game in front of. Say there are 2 million groups out there. At my current rate of downloads (200/mo), it would take 1,250 years to get all the GMs out there to at least look at my games. (Better get to work!)
