You alright man? I keep seeing small damage numbers coming off you

I have! I think I got as far as the arc where she figures out she can use the sword as a hoverboard and do sick aerial stunts

I got grilled mackerel out of a train station vending machine once. Anyway, yes that’s absolutely a class specialisation

I’ve been reading Mazumeshi Elf and it very much does “guy who is trying to introduce cheese to a fantasy race of nomads but has also realised he’s vastly overestimated how well he understands the mechanics behind how cheese is made”

Same wavelength! I’ve been reading about the Spartacus slave revolt in Rome so now I’m picturing bands of catgirls roaming around with all the OP armour and weapons they picked up off their shitty masters

I was thinking of For The Dungeon! but my vision here is that the hero is straight up invincible and the monsters are resorting to stuff like setting up cooking tournaments and games of chance, or increasingly complicated comedy skits

No but every time I use his patented “list of dumb rpg suggestions” bit he does send me an invoicr

- revenge fantasy rpg where you’re freed catgirl slaves who go around murdering isekai heroes who think it’s okay to buy catgirl slaves because they’re “one of the good ones”
- Oops All Vending Machines

Ideas for people looking to join the isekai TTPRG wave:
- players can only take terrible gimmick RPG classes and have to figure out what combo of upgrades makes them good actually
- you’re all monsters in a dungeon that the overpowered hero has been grinding nonstop
- slow life farming sim (horny)

Thanks for your help! Here’s what I’ve found:
- Girl Underground
- This World Keeps Summoning Heroes
- Many classes, few systems

And:
- DIE is not an Isekai
- DCCarl is not an Isekai
- Any TTRPG could be an Isekai, why bother
- All TTRPGs are obviously Isekai already and I am a stultifying buffoon

Thank you! I’ve been running convention games of it again and everyone picks up the humour pretty quickly. Half of the mechanics secretly double as roleplay prompts so everyone can butt their ridiculous hero protagonists into each other.

My take on why the genre hasn’t been more popular is that isekai provokes a strong polarising reaction - when I do find forum discussions of my game, they often have devolved into discussions of what people hate or find stupid about isekai. The flipside is that people who do like it, LOVE it.

I first started designing This World Summons Too Many Heroes!! as a gift for a friend who was also disappointed with the limited options for isekai TTRPGs! The LUMEN system was designed for video game-like power fantasy action, so it seemed like a natural fit.

Great opportunity to invest early in wildly high concept RPG themed sci-fi but also in retail hell moments like this

Six sessions into running this Adventure Path and I’m having a great time! We’ve done gladiatoral combat, feasting contests, fought off a sea serpent, and acted out the final moments of a hero’s life with their ghost to send them to the afterlife. Great sword and sandals vibes.

If you're running an RPG campaign, a great thing to do is to maintain some kind of journal of characters the PCs meet but also to give them star rankings like they were gacha game characters

SURPRISE!

I had an idea on Tuesday for how to do the Perfect Space Marine RPG, so I wrote the Perfect Space Marine RPG.

It's both a shitpost and a dead serious game. And it's, uh... 34,000 words long?

Anyway enjoy!!!

Content-wise, there’s quite a bit here, a lot more than you’d expect from a high-concept comedy RPG in fact. Locations and NPCs, from goddesses all the way down to a kobold with a gun (who will shoot you, with his gun), all come with a passel of motivations and story hooks. Of all the parts of this game, I think the world as presented is surprisingly my favorite bit. It’s not always consistent, but it’s consistently entertaining. What more could you ask for really.

Kobold With a Gun getting a lot of love, as is appropriate

It’s Heroing Time!
And then he heroed all over those guys

To build your very own isekai hero, start by choosing an Archetype.
The Bystander: Whoops! You weren’t even supposed to be here today, but you were standing too close to someone else being summoned or were hit by Truck-Kun and got sucked into another world by accident.
The Demon Lord: Evil cultists summoned you here to rule the world, but you didn’t care for their vibe and you look terrible in black leather, so you dipped.
The Hero: You were brought to Ceria to defeat an ancient evil. You blew through that quest easily, of course, so now you’re just looking for something interesting to occupy your time.
The Myth: You’re never alone; there’s the spirit of a great Cerian hero or magic beast in your body. Once per adventure you can flip them in so they can wipe up the bad guys for you.
The Noble: You occupy the body of a previously existing high mucky-muck, who by all accounts was kind of a snot. Now you have to navigate their life and maybe make things better for the people around you.
The Reader: Ceria was the subject of your favorite book or video game in your past life, and you know more about it than even the people who live here.
The Reincarnated: Only your spirit arrived, without a body. Unfortunately the summoning spell doesn’t do “making a human body” very well, and you now have the form of something completely different.
Tragedeigh The Tragedy: You were summoned by someone very bad, who used you for very bad purposes. You managed to escape but now you have terrible scars and trust issues.
Each Archetype includes a choice between two special background-style benefits. For instance, the Noble can choose either Disowned Heir (get better starting equipment) or Villainess (any attempt to bully people always uses your best Attribute).

I had a player at PAX make a minmaxed Assassin + Tricky tag build and I’m very relieved that it’s now working properly as a minion/drop farming class instead of a stunlocking angel of death
