Thomas Manuel writes about "Mike Pondsmith's Other Games" (paywall), particularly Pondsmith's tabletop work from the mid-80s to mid-90s, including the Mekton games. Thomas surveys these games, engaging with them critically: what's innovative, what's problematic, what characterizes them.

The ending of this article is pretty great!
Nick Gralewicz, of the famed HOME mech rpg, is about to release A Perfect Rock later this month, an Outer Wilds style RPG about finding a new planet to call home. Is A Perfect Rock mecha? No, but you can choose for your explorer to use a mech suit in the game, and Nick offered a very cool "Mech Survey Team" patch during the Kickstarter. Recently, Nick shared a video about the print edition, which is worth checking out:

Featured Mecha TTRPG
This month's featured ttrpg is Girl Frame by Isabelle M. Ruebsaat.
Girl Frame is a powered by the apocalypse (PBTA) tabletop RPG about lesbian pilots, forced into half-living mech suits and sent by their Handler to kill Gorgons - eldritch beings from outside reality.
This game launched back in October 2025, and it was immediately popular. Since then, it has been among itch's top-selling tabletop RPGs. I caught bits and pieces of it in various discords as it was being developed, and I was struck even then, without having seen the whole work, at how good Isabelle is at writing.

Opinion
I recommend this game! The writing is excellent, and Isabelle has lots of really clever bits in the game. I personally enjoyed how the "handler" (GM-type role) becomes a character and can even move to another player at certain points in the game.
Also, I think the game is an interesting example of “uncomfortable game design," which creates "positive negative" experiences — experiences that can be distressing but also gratifying because they create new insights.
Next month, I'll be featuring a post by a guest writer, someone who has written an excellent series on mech rpgs before. What will they write on for April?
An interview with Isabelle M. Ruebsaat:
What about the mecha genre appealed to you for a game about gender?
Isabelle: I think mecha has always kinda been about gender, but usually about struggles with masculinity in Evangelion, Gundam, etc. That said, I think there’s large elements where putting yourself in a body that isn’t your own is a very genderqueer theme already, even without prior context.
Girl Frame promises toxic power dynamics. Can you say a little about how you build themes of hierarchy and control into the PBTA framework?
Isabelle: Part of Girl Frame was me wanting to take the common criticism of “PbtA is restrictive” (a criticism I disagree with) and apply it intentionally to the system. The basic plays do not allow healthy solutions to problems, the Status structure encourages trying to stay on top, which can only be done by pushing others down.
Through the Tags system, you have a lot of control over other character’s rolls. You can Tag someone with “loser” and then make them be more of a loser. It encourages thinking of the other PCs as tools moreso than friends.
I think one of the biggest elements is the Handler. The traditional GM having an explicit antagonistic PC with direct control over the other PC’s lives creates a really messed up unbalanced power dynamic.
What is unique about Girl Frame?
Isabelle: Truly unique? Very little. I draw on design lessons from a LOT of other games. If you’re not as nose-deep in indie ttrpgs as I am though, you might find the heavily toxic social focus, the oppressive atmosphere, multiple PbtA playbooks/approach to move design, or the PC-ification of the GM role to be elements you haven’t interacted with before.
But I don’t really see Girl Frame as doing much that’s unique, my goal was to create a well-made synthesis of what I’ve learned from other games over the 15 years of playing rpgs.
Who should try Girl Frame?
Isabelle: Anyone who finds interplays of gender and oppression and power dynamics interesting, who is not afraid to get a bit messy with their play.
What inspirations or touchstones does Girl Frame draw on?
Isabelle: The big 3 are the anime Evangelion and 86, and the video game Armoured Core 6. I’d also credit the anime Witch From Mercury as putting lesbian-specific play in my head
What other games do you recommend?
Isabelle: Too many to count! But Girl Frame definitely draws some inspiration and lessons from a bunch of PbtA systems:
- Under Hollow Hills
- Praise the Hawkmoth King
- Monsterhearts
- Dream Askew
- Apocalypse World/Burned Over
- Apocalypse Keys
- Fellowship
Another couple other personal favourites of mine are the Yellow Curtain (which I tragically missed out on getting a physical copy of), The Far Roofs, and GLOG.
