Well, I have had no contact other then that single e-mail for the game. But it's not like I know the guy, anyway.
One player of the game did e-mail me to say how great he thought the game was, and he looks forward to "being on the run for the next game". He thinks the DM will be busy again this weekend...
So...maybe run the game again. I'm so tempted to start the game with Tyr coming down and ploymorphing all the PCs into deers and then seting a pack of wolves on them to rip them apart. Then maybe see if they want to play Munskin for the next couple hours.
But at my heart is a Teaching Railroad DM of horror...so, I have my forced game plan. Start off with the PCs hidding in the caves...and have some Dumb and Dumber bounty hunters after them(to set up some illusioniusm for the players). Then toss a nice...Adjustment Bureau, TVA, Timecop and "Put Things Right that Once Went Wrong" plot at them. Toss in some modrons "fixing reality" to attack the characters. Then have alternate copies of the PCs show up. They will claim to be from a "good" alt world where they are not murderhobos and are here to put right what once when wrong: The PC slaughter fest. And when the PCs fall for this....they discover the alt PCs are really from the "evil twin" world where the alts did the slaughter and are now out to slaughter all their alts across reality.
This lets me show them their characters made much better and like three times as more powerful. I can tell by looking they made their characters using only the 'core' 5E stuff. The players will either kill the double characters or, more likely have their characters killed by the doubles. Each way, they will see much better and more powerful versions of their characters.
If the characters die, and they players walk out...oh well game over for them. If they stick it out, I'll do the spin that they can "come back" as Alternative Alternative versions of their character, but offer them more class options, items, spell, ect to remake their character.
Maybe the players choose to Put Right What Once Went Wrong. Maybe they choose to run with their new and improved 'stealth' characters. Or something related......should fill up the game time.
