My One Shot went over really well! Everyone had a lot of fun and it turned out great. One of my players powerbombing an enemy from a 20ft guard tower right at the start really set the tone for the rest of the encounter.
Nice! What was the premise?
I was a player in a "Lost Mines of Phandelver" campaign, and one thing leads to another, and we're homebrewing the fuck out of what is a meant to be a linear and railroaded module. One player is going to be missing for this week's session, and I'd expressed interest in DM'ing myself at some point, so he offered that I take over as DM for one week, constructing a scenario that was relevant to what was happening currently.
Basically, an NPC had asked the crew to handle some Cultists, and ORDINARILY this would mean kicking them out of the little shack they'd occupied, but I expanded that to be a fortified compound with several buildings and multiple encounters throughout. My own character was mysteriously absent for this oneshot, so my DM brought over his own character from an entirely different campaign, and I ran the entire thing for them. They quite enjoyed themselves, from the impromptu Pro Wrestling, to the totally pointless pony I placed in the middle of a field, to the cleric getting jumped by four zombies, and the final encounter with the Cult Elite, where it was revealed little by little that the Cultists weren't just evil bad guys, but plausible good guys that had interpersonal relationships with eachother and a pet cat. All the Cultists except the leader were killed, who was captured alive. Next week I'm returning as a player and my DM is taking the reins again, so he gets to work with the results of that one shot.
I really enjoyed it, and I think everyone enjoyed it. Though I didn't get to surprise anyone with a Mimic encounter I had prepared though, I wanted to do that but the session ran over our normal schedule by an hour and so intended encounters had to be pruned off the agenda so that everything could be wrapped up in one night.
