All of that is very true, Sky.
Personally, I just don't subscribe to the mentality that "new is ALWAYS better." Sure, there are some newer figures that are great. (I really do like Dusk and Dawn a LOT.) But I think part of what figure to use also depends on what type of art the person makes. Do they produce storyline illustrations? Do they just do whatever the muse tells them to? Are they an animator? Still renderer? All of these impact figure and clothing/accessory choices.
Security of the online stores can impact some buyers willingness to buy, yes. But to be fair - again - even brick and mortar stores have been hacked and had their security compromised. Hannaford, Wal-Mart, Home Depot, just to name a few. Heck, even the TSA had it's databases hacked into. I know this because my Bear used to work for the TSA, and we got all the notifications about how personal information was compromised and what services they were offering in case our information was used without our authorization!
So for me... the security issue, while it means a fair lot, I'm also a realist and I can't blame a store for the actions of some nutjob jerk who decided to hack into it. Security is only as good as the human who sets it up - and whatever security you set up, eventually another human will find a way to break it. It's just the nature of it.
The bigger thing driving people away from making purchases of pre-made 3D content, honestly, is the kind of content being produced. Daz produces pinup content. I'm sorry, but four inch spike heels on the boots of a combat armor outfit is not only ridiculous, it's offensive. And it's gotten old, VERY old, long ago. There is a time and place for high heels - armor, outdoors/adventure items are NOT that place.
The same old same old content being produced over and over - again, people are sick of it.
The constant new-figure game - every 12 to 18 months or so Daz puts out a new figure and you have re-buy ALL the basic utilities just to begin using it. Again - people are sick of it, and they aren't buying as much as they once did. It's a profits game.
The HW figures are pretty steady. Could they use some improvments? Absolutely. But they're still fairly new, and from what I've been seeing.. more folks are willing to try them out now. A lot of people pretty much assumed they would go under in the first six months of release. I'm actually really tired of defeatist attitudes like that. Give them a bloody chance! Don't sink the ship before there's even a hole in it.
I just think with something like figure choices, every artist is different, and there's too many variables. I might buy G3 clothing. So sure, the G3 sales are going to look like they're doing well. But do I use it ON the G3 figures? HECK no, I sure don't! I buy G3 clothing to use on Genesis 1!! LMAO But if you go by the numbers alone - sure, the G3 stuff is selling. They don't take into account how many buyers are using the items on the native figures.
I've made use of M4 and V4 stuff on Dawn and Dusk, which is a real pain as a DS user, because the autofit utility pops up when you fit a Poser Dawn outfit to a Studio Dawn figure, and we don't have a lot of good projection templates yet to use on the DS side of things. As a result, some stuff made for Poser Dawn, for instance, does NOT fit well to Studio Dawn. Same can be said for Luna and Dusk. Especially Luna and Dusk. LOL
So figure choices are just too wide of a variable. There's too many things that impact an artist's choice to use one figure over another in a piece of art, and no market, IMO, can properly predict those choices. Those of us who have been around enough years... well we're used to kitbashing things to make them work, because back around the P4 figures and the V2/M2 eras, that was often times the only way to get anything done.
The newer artists; the ones who have come in around the time of Genesis 1's and Genesis 2's... they often times don't even understand the difference between a "figure" and a "morph/character" for a figure, because Daz bills every new character morph as if it's a new figure. I'm sorry, but no, no it's not. Victoria 7 is not a brand new figure. She's a morph built on the G3 Female figure. Big difference. But it's a difference that some of the newer folks don't understand yet.
I think the G3 figures are good. Just like the G2's, the G1's, and all the figures beforehand. They're all nice figures to one degree or another. The HW figures are good. But just because a figure is "good" doesn't mean it's usable for some folks. If the figure lacks content support, it doesn't matter how good it is, it's not going to be used. If someone has lots and lots of time and money invested in one figure base, and the next round of figures lack the things they need - then they're just NOT going to switch over to the newer figures.
Every artist uses what they find the most useful to their art. And when you start getting into things like that - the Human Factor - it's unpredictable, and no market, no economist, can predict what people will do. Human behavior is unpredictable at times. Especially where sales and money spending is concerned.
