I wrote a game called On Mighty Thews. It's a pulp fantasy roleplaying game that's player-driven and fast to play. Here is a pretty good review, and here is another one.
I made a little thing called the Pulpy Primer to help people get the vibe.
Nod is a kind of story-game thing I wrote. I feel like I never quite got the physical layout right, and it's harder to play than it should be, but there are some good ideas in there.
TWSADODITA is a one-page story-game kinda thing. You can you can download it for free. I recommend using these rules for building a party.
This is a very small Apocalypse World hack for doing Conan stuff. Download it for free!
Like everyone, I have my own DnD rules I've been tinkering with for the last ten years or so. I make cute little playbooks for each of the classes. You can read more here.
I trawled through every year of the One Page Dungeon Contest entries to compile this spreadsheet of what I think are some of the most suitable for wargaming-style D&D.
I figured out how to beat low-level Dungeons and Dragons, and I wrote it down in this handy list of axioms.
The Homebrewer's Pantry is a catalogue of rules collected from D&D and D&D-like rpgs from the 70's to today. You can download it here!
One Million Dungeons is a dungeon generator for fifth edition D&D. I like to think it's a bit better than other generators at producing sensible dungeons with a bit of story to them. There's also an encounter generator for 5e which I found very useful as a tool when I played that game.
Maybe you'd like to get in touch about something? Email me at simoncarryer@gmail.com, or try @simoncarryer on Twitter if that's your thing.
When I must, I do things that aren't related to role playing games. You can find that stuff here.
