I tried to find some kind of definitive source that would say how many people are estimated to role play but so far have found none. I was wondering if anyone here knows. I saw some numbers for back in the 80's but not anything more recent.
There are a couple of ways you could try to guess at this, possibly take sales for games that were made in the last five years an then try and guess what percentage of the market that is.
Any thoughts on that? I'm pretty sure someone is either going to immediately answer with a link on wikipedia or some other obvious place or nobody knows.
