Why do people keep saying I am making assumptions?
Fact: WOTC claims there are 6 million D&D players world wide, for many years now.
Fact: WOTC admits to selling only "a few hundred thousand copies of" their core books.
Fact: WOTC has publicly claimed that 4E is out selling 3E.
So if all of those are true facts, I am not making any assumptions except for what exact numbers might be. Its still a fact that there are far fewer than 1 million players of 4E. If 4E is indeed already outselling 3E we now know 3E never had more than a few hundred thousand sales as well.
So we now know for a fact that there may be 6 million D&D players out there, but most of them (4 million+) NEVER played 3E or 4E.
These are not assumptions, these are facts proven by the numbers given by WOTC themselves. This is taking into account 1 set of books per group of 6 players, since that is the only way they can even approach 2 million players, let alone customers, with only a few hundred thousand sales of their core books.
These are not assumptions, but facts derived from the numbers given by WOTC themselves.
Do the math, do the estimates based on various estimates of books per group, etc... the numbers prove what I say.
