In any event, since the success and popularity of the Adventure Path line has been alternating between slow and fast growth spurts but hasn't really done a decline yet... I suspect that it IS enough.
That's pretty remarkable, given the APs have progressed from 'standard' (though excellently written) adventures through the occasional off-the-beaten-path story, survived a new game launch and more recently branched into much more niche genres (pirates/asian-themed). I would have predicted at least one of those APs would have resulted in a drop in sales.
.Glad to see I was wrong (again!) Nice work. :)
