Wait... you've spent hours looking for pictures for your mods, and you don't even look at them? Huh. Well, thanks for finding the pics for *me*, anyway.
And you're right; it's not strictly an argument. It's more of an opinion, but one that may be pertinent to the discussion.
As for whether random girls are supposed to be the main part of your brothels, well, that may have been (probably was, actually) the original goal but given that the girlpack mods *do* exist now, I would think that the assessment should change accordingly. The girls are there now, and I think it's safe to assume pretty much everyone that plays the game for more than an hour has at least a couple of them downloaded. Given that there has, indeed, been a change the game should probably change with it - that's why necno is using beta releases to begin with. You may disagree, but I would guess (perhaps wrongly) that necno does not. Given that a change should be made, the question is "what change?", and I (along with some others) am only giving a couple possible answers to that question.
And as for balance: I think that *IF* a randomizer is created, it would be a LOT easier to balance than a lot of random mods. Mods, by definition, are not standardized to the game itself but to the mod author's intentions - this idea would reverse that once again.
