Personally, I don't think WBW made this stuff for laughs, I think he made it cause he thought that there was a gap and possibly an interest. Maybe he was thinking of seeing if MMP would be interested. Who's to say we really don't know it's all just speculation. Even when he was introducing PTO stuff before AH made COB (let alone the 1st edition of the rule book) he never really stated anything other then producing stuff. Odd I know, because other TPP have come right out and have said this is what were doing and what we are trying to accomplish. Even back when WBW switched to PC war games (Tanks! and Steel Panthers and more specifically SPWAW) I don't recall him recruiting, marketing or saying too much of anything, just pumping out scenarios and campaigns like a rabbit.
Again, further proof of this seems to be the now Zulu and 1900 modules he is making.
