Why does there have to be only one figure? Or one set of figures?

Sixus1 is a top vendor. So they must be doing something right to have earned that status over the years. Clearly they sell enough content and have a decent sized fan base.

Not everyone that uses Poser intends on using it for ultra realism. A lot of people like it for rendering more stylized cartoon and sketch style renders as well. How realistic is RWBY? A figure does not have to look like a photograph in order to gather a following and be considered a good figure. And it doesn't have to be a "vicky killer" in order to garner it's creator a decent living from it. So what if other vendors don't support this or that figure? As long as the artist that created that figure continues to support their own creation with add-on content, then there's a market for them to continue providing that content to the fans of their work. And in the end, the only thing that really matters is the fans of an artist's work, not all the other vendors that decide to snub their noses at their work, or all the other people who don't have anything better to do with their lives than to discredit other people's efforts. The whole purpose of being an artist is creating art that you enjoy creating. And if you can earn a living while doing it and gather more fans of your work then that makes it even better. It doesn't need to be a popularity contest.
