Vilters has hit on a major point that I omitted, these days it has to be different. 

For example Agatha by 3-DArena, there are a few older V4 characters out there but not many.  For M4 how about Alvaro by Tempesta3D for someting different from the twenty something male pin up or Nalfaar by Vyktohria, 3D needs some villans as well as hunks.

I think this also become more imprtant as you progress.  In the recent sale here at rendo they 65 pages slae items.  Scanning that many V4 chracters the front promo page has to look a little differetn to stop you continuing to scan.  The same can be said when scanning new items, the more you buy the more smoething has to be different to get you to reach for the credit card.

 

 

I use Poser 13 on Windows 11 - For Scene set up I use a Geekcom A5 -  Ryzen 9 5900HX, with 64 gig ram and 3 TB  storage, mini PC with final rendering done on normal sized desktop using an AMD Ryzen Threadipper 1950X CPU, Corsair Hydro H100i CPU cooler, 3XS EVGA GTX 1080i SC with 11g Ram, 4 X 16gig Corsair DDR4 Ram and a Corsair RM 100 PSU .   The desktop is in a remote location with rendering done via Queue Manager which gives me a clearer desktop and quieter computer room.
