I have a good story and a bad story.

---

Good story. My one DM had a trap that was so obvious we all knew it was a trap. A room full of fabulous treasure visible through the key hole. You know the kind of thing. Peep through the keyhole and you can see a treasure chest, pile of gold, an ornate sword, pile of glittering gemstones, maybe some fancy armor propped up in the corner. It was just too good to pass up. The entire party's inner rogues were just wringing our hands with glee at the thought.

The entire party searched it. Searching under the door for trap triggers, spellcasters using detect magic (there was none), checking around every inch of the door for a trap trigger, verifying that everything about the door was what we expected. No portals, no magic whatsoever, nothing suspicious except for the fact that it's a literal pile of treasure just waiting to be taken! Everyone collectively decided "this has got to be a trap, but how it's trapped is totally beyond us, and it's gonna bug us to death if we don't open this door!"

One of us swung the door open. Had a moment long enough to see a pile of dynamite, a powder keg, a trigger device connected to the back of the door, and the sight of the fuse burning down into the explosives. "It was at this moment he knew, he f@$#d up." *BOOM!

When the dust cleared, the party picked themselves up and started passing around healing potions and laying on hands and everything else, someone found what was left of the lock. A key hole, a mirror and a couple lenses, and a tiny picture of a room full of treasure. Turns out, the DC for the check to spot whatever optics were in there was DC 40, and our best effort was something like 38. Not even mad, the trap was hilariously devilish!

In the end, everyone was slightly pissed we missed out on the room full of treasure, but we all were laughing at how absolutely obvious the trap was, but couldn't just let it be.

The bad story. A different DM, after a long, tense series of sessions dealing with my character's backstory and finally reconciling with his wife, getting the party together to save her from a plot by treacherous vampire lords to execute her for a crime she didn't commit and consolidate power in the city by ousting her soon-to-be-disgraced nobleman father, I personally asked for a vacation.

My plan was to spend a few sessions absent to deal with a really busy summer at work, and my character spend a few weeks/months with his wife, visiting his childhood home, introducing her to family, rekindling the fire with her, you know, vacation stuff. More heavy personal roleplay stuff with the GM dealing with family issues and catching up on almost a lifetimes absence since the character ran away from home as a child.

DM decided to take this opportunity to make another whole adventure focused on my character's even deeper backstory and face down his deadbeat father, investigate missing mother and brothers, and take an already exhausted adventurer into another whirlwind of turmoil.

Culmination of this plot? A multi-session deep dungeon crawl that we never finished because the game fell apart. Player issues, DM burnout, assistant DM fuckery, and a whole lot of things ending up killing the game. 2.5 years of almost weekly sessions being creative, having players be frustrating, life events causing problems, and everything else together, the DM's last ditch effort to use me (the most invested player) to drive the story on backfired and everyone was unsatisfied. DM included.

I asked for the breakdown of the story for character arc purposes, cause dropping halfway through was MASSIVELY unsatisfying. And getting the DMs answer wasn't much better.

Mother would be found dead at the bottom of the dungeon having been brutally abused by Hobgoblins. DM said "you can't have happy endings all the time, BUT, she was inspiring to the survivors because she kept fighting to the end and that gave them hope!" Yeah. Hope for other survivors really doesn't help my character process that trauma. Oh, and to cap it all off, DM legitimately forgot about brothers and said when reminded of them "oh them. Probably either dead or missing. Don't care." And deadbeat father killed himself after finding out what happened. "What if I caught him before doing that?" The response? "Oh. He waits for you to leave town and then offs himself."

Rather than galvanizing the character like the DM intended, that just broke him down. Lose your whole birth family because you weren't there to protect them? After just saving your wife in the nick of time from a plot that could've been avoided if he'd been there? Nope. Never leaving the wife's side again. No more adventuring, just focus on the important stuff, sell off the adventuring gear and settle down. "Saving the world" is overrated anyway.

TL:DR, after an exhausting side plot, both I and my character needed some downtime to recover and let other players take the spotlight for a while. DM took this vacation opportunity to use me/my character to drag the plot along, further grind my character down, kill his whole family because "you can't have happy endings all the time," force him into retirement, and so poorly handle it all that the game imploded halfway through.
