So many. And the answer to all “why nots?”. Time. It’s time. So off the top of my head

Eat the Reich - “The year is 1943. You are a team of crack vampire commandos with one mission: drink all of Hitler’s blood”

Conan 2d20

Legend of the Five rings (5e)

Stoneburner - Deep Rock Galactic the TTRPG

Vaesen - Call of Cthulhu but rooted in nordic mythology

Heart the City Beneath - an award-winning complete tabletop roleplaying game about delving into a nightmare undercity that will give you everything you’ve ever dreamed of – or kill you in the process.

Lancer, I need to finish my Curse of Strahd campaign first…

Paranoia. I’m afraid I’ve hyped it up too much internally and there’s no way any real play will meet my expectations.

I’d love to play in a Vampire: The Masquerade campaign, or to GM an Avatar Legends campaign. But I’ve only got one gaming group, we’ve got one ongoing campaign, and even getting them to play Pathfinder rather than D&D was an unusual and new experience for them.

Any gumshoe game, probably something shorter than Nights Black Agents: The Dracula Dossier. If I set it in my own setting, I’d like to use Bubblegumshoe to do my own telling of “Tomorrow When the War Began” basically what happens if on the summer camping trip after your last school year, your country is invaded. I can’t quite tell how good Gumshoe is for homebrew settings however.

My other want is to run a worldbuilding game such as the quiet year, for the queen or microscope, hacked to set up a concise and thematic noir mystery inspired by fiction like Disco Elysium, The City and the City or The Nice Guys, with a rich and vibrant world that the players are invested in as they built it. I’m tempted to hack the bladerunner RPG by Freeleague for the actual police procedural afterwards.

Three-way tie. Unfortunately there hasn’t been movement on any due to personal stuff, but hopefully soon:

• Pathfinder 2e for a modern D&D-type experience. (Not to yuck anyone’s yum, but I have plenty of gripes with 5e.)

• Dolmenwood. Currently awaiting delivery of the Kickstarter. For those old-school D&D vibes.

• Burning Wheel. My favorite game I’ve never played, even after owning the books for nearly two decades. :P But for real this time!

Electric Bastionland has been the RPG I most want to run ever since I bought it years ago.

After watching a surreal Acid Western (which started out deceptively straightforward and veered endearingly off the rails by the final act), I’m itching to run In The Light of the Setting Sun: Bonanza Edition. But I’m at the end of my current FIST: Ultra Edition campaign and don’t want to rush anything. :D

Mage the awakening 2e. I had a game of it for about 20 sessions, but it fell apart. One player never really learned the rules and was easily frustrated, which is a bad combination. She also straight up said she wasn’t going to read a 5 sentence paragraph clue. I definitely had some fumbles, but chief among them I think was overestimating how much they were willing to think about clues and text. They wouldn’t even taken notes between sessions, and then would forget.

I also want to do Fate, but it’s been hard to find a group. I got my old DND group to try it, but I didn’t really like playing with them. I have a new group, but someone just dropped so now we’re down to 2 players again. It’s a nice game though.

wanderhome! i don’t have a group of friends who are cringe creative enough to do a fully nonviolent game

Anything sci-fi, using the Savage Worlds system.

I can’t find players. Locally, I can’t find anyone playing anything other than 5e. Online, I’ve been able to find players for various non-5e systems, but haven’t managed to organise a sci-fi SWADE campaign (yet).

I’ve always loved Shadowrun’s lore. I’d love to play it, but I don’t think I’d enjoy the crunch.

I borrowed Blades in the Dark flashback mechanic for a 5e heist. It worked out well, so I’d like to try the full game.

Ten Candles also sounds pretty cool. But I play exclusively online, so that won’t work for now.

Eclipse Phase. It’s a d100 body-swapping cyberpunk scifi horror game partly inspired by the Altered Carbon novels. In the default campaign the players are part of a conspiracy to steer humanity away from tampering with X-threats like alien viruses and tech left behind by hostile superintelligent AI.

I still might run it. My group cycles through GMs, each one of us running a campaign that can be years long. Last time it was my turn I ran Genius: the Transgression, next time could be Eclipse Phase.

I’ve really wanted to learn Delta Green so I can run a SCP story I love (What Happened to Site 13?) and at the end the site teleports out of the world.

Then I’d run a fantasy campaign that is cleaning up the mess they left in the Delta Green one.

Some day I’ll probably run Fate. I’m currently playing Fate as a player, but some day when that campaign’s over I’ll probably start a Fate game as a GM.

As to the “why haven’t I run it yet”, mostly because it wasn’t really on my radar until recently. Once it was on my radar, I happened to stumble across someone else advertising to run a Fate game, so I focused my energies on getting into that game as a player.

I’d love a go at Crown and Skull by Runehammer. It looks really interesting. I’d like to play it before I run it and, frankly, just don’t have the time.
