Hi there! I'm a game designer and publisher who's used Itch as a consumer and have been looking into hosting products here. I'm mostly chiming in to reiterate the good ideas other folks have shared. To clarify: I'm sharing info that I think is most relevent and efficient; there are lots of great ideas suggested but some of them may be edge cases.
Broad Designation: "Analog Games" and "Tabletop Games" are the most commonly used but whereas "Tabletop" only includes RPGs, board, and card games, "Analog" also includes LARPs and other kinds of games. Analog is probably the best best.
Sub-Sections:
- Board Game
- Card Game
- LARP
- Roleplaying Game
- RPG Supplement
- RPG Utility
- Zine
Genres/Categories:
- Campaign
- Family Friendly
- Fantasy
- GMless/GMfull (GMless is more popular but GMfull has a decent sized following)
- Horror
- Low Prep
- Micro Game
- No Prep
- One Shot
- Post Apocalypse
- Sci Fi
- Solo RPG
- Story Game/Storytelling Game
- Superheroes
- Western
- Worldbuilding Game
3rd Party Publishing:
- Cypher System
- Fate
- Forged in the Dark (FitD)
- Open Game License (OGL)
- OSR (Often "Old School Renaissance" but the acronym has basically moved past easy definition)
- Powered by the Apocalypse (PbtA)
- Savage Worlds Aces: for official licensees of the Savage Worlds RPG (may not be possible due to licensing restrictions; contact Pinnacle Entertainment Group for clarification)
- Savage Worlds Adventurer's Guild (SWAG): for fan products for the Savage Worlds RPG (same potential licensing issues above apply)
Misc. Ideas
- Print Products: I don't need to sell print products on Itch but the option would be nice. Working with a 3rd party like Lulu or Lightning Source would be amazing.
- Mailing Lists: Not sure if Itch already has something like this but I'd like to be able to send an email to everyone who has purchased my products (only if they consent to receive email, of course).
- Forum/Social Media: I've saved the biggest ask for last. Google+ an oasis for thousands of people in several parts of the RPG community but it's shutting down. Alternatives (facebook, Twitter, MeWe, Discord, Slack, etc.) all have interesting opportunities but none of them are a solid replacement. Some kind of (searchable!) forum or social media space where tabletop gamers could chat (grouped by discussion) and share news, blog posts, etc. would be truly wonderful.
Thanks so much for taking this step, Leaf! It's the thing that's made me finally decide to give publishing on Itch a try. Looking forward to what you come up with!
