My first impression with the character builder was disappointment, but understanding, that the races were locked behind paid content. But, I was willing to give it a shot with the core races. Then, I realized the feats are also locked behind paid content. I stopped there.
I get you’re a business, and you have to make money, but from my point of view here’s how it looks. I can wait to use your character builder until I can afford to purchase all of the books, or I could just use Pathbuilder and have ALL of the options, and use Nethys to access rules and just slowly purchase physical or pdf copies as I go.
Right now it seems like your target audience is the people who have already purchased most of the books from you. The character builder could be a great way to bring in new customers that haven’t already made a significant investment with you, but might if given a good reason.
Perhaps, if all of the content were unlocked during beta, and I was blown away by the character builder, I would see a point in purchasing said content from Demiplane, but since I can’t build a character with as many options as I can with pathbuilder, I have no incentive to test the product for you which is less likely to result in sales for you.
Actual feedback about the character builder: it’s too linearly designed for my tastes. Too much back and forth to accomplish the same thing that can be done more easily on a spreadsheet or (sorry, but…) Pathbuilder.
