The key is finding 3 or 4 other adults that understand the value of consistency. I’ve been in a weekly game since before COVID and we simply don’t make other plans on that day. No “eh, it’s just D&D I can skip it to go to the movies”. No grief for legitimate reasons to miss a session (but we try to do a replacement activity to keep the schedule rhythm) because we all trust the rest to take the commitment seriously.

There’s people with children in the group who make it work. If you can’t handle a weekly game you just don’t want to do it enough. It’s not a matter of convenience.
