Almost 100% of the time I want to get to a damn product list that's clean, concise and easy. I click starfinder, I have to navigate off a page that takes me to core rulebook and then spend 5 more minutes trying to find a product list.
I just want to browse products. If I want to see the core rulebooks, I'll click them. The header menu should just take me to a nice list that's sorted by:
BOOKS
ADVENTURES/MODULES
OTHER
