Speaking as the parent ….
I intended to convert our guest bedroom into a gaming room for my kids. We got excited over the things we could do to decorate and turn it into a real game room (maybe leave it usable as a guest room on the rare occasion). Then when it came down to it, that would mean I’d never see them. Instead we added banquet tables in the family room near the TV, so at least we’re all in the same room.
We do occasionally game together so that was even more handy
And it helps a lot with ventilation plus I’m lazy
