Since March 2020, virtual tools and tabletops are the primary media many people use to engage with our hobby.
No points for guessing why. The fact of the matter is that since COVID began, many people have shifted away from in person games and physical tools to remote games using digital tools. Since 2020, 90% of my games have been virtual, and I’ve quit using paper sheets entirely in favor of D&D Beyond.
Virtual tools are how people engage with our hobby now. It would be tone deaf to the state of the industry to disallow questions about them.
We handle questions about paper sheets, dice, LARP props, miniatures, and battle maps. Why? These are the things people use to engage with the hobby. Why would virtual table tops and digital tool sets be treated differently?
To be clear, I do not mean to say that the recent advent of VTTs changed anything for this question. Online tools have been on topic since the stack's inception. This question from 8 days after the site's launch is about how to use an online tool: How do I manage created content in D&D Character Builder?
