true, but it's only $100 for the $5 addition by request.  i think there are figures he just adds.  that is, i'm not sure daz paid him to add v4 or the mill baby.  unlike other figures, ww for v4 is more of a detriment to the market than a positive force to buy.  in the support forums is a thread that's just a long poll of requested figures (some of which he's added).    for instance, i find it dubious that the creator of eve4 paid anything for her addition. and i'm not even sure dacort has been around to even know about ww, let alone pay for natalia support. 

look at the list of supported figures. granted, philc is a complete marvel at how much he does, but if it took a week to add each of those figures, i doubt it would have ever been released.  and kamilche worked (and works) on making games at the same time. 

let me put it another way: if you came up with an app that transferred morphs but supported 1/10 the number of figures ww does, people would probably still be interested.
