[@Skwint] Would you have preferred we spent effort and time investment into this venture, then found out the DM is a child?

I offered to leave. In what context does a single player, actively offering to bow out, make anyone besides a toddler decide, "Fuck it, I'm taking my ball and going home!"?

No, I'll count my blessings and call it luck that I found out this was a train wreck waiting to happen before I invested time and effort into it. Thank you.
