Pretty much what the title says, I’ve been looking for places to share/get feedback on some TTRPG systems I’ve been working on, is this the right place?
Yep, tell us about them. Not only the right place, but the best place. Maybe not the most positive happy place, but the best place if you want feedback from people that have played or read every system there is.
So I've made one very simple system for a superhero-based TTRPG, and I want to try my hand at a sci-fi system. I've played Traveller before, but my goal when designing RPGs is simplicity and ease of learning, so while I want to take inspiration from Traveller, I've been trying to work with something easier. (I can post examples of both systems in a bit)
If you mean "right forum on this site" then sure. If you mean "what forum online might be a good place for discussing RPG design?" then you might take a look at RPG.net - they have a dedicated subforum on the subject that could also be useful, although it doesn't see a ton of traffic.
