I‘m almost certainly not the only one on this forum to be taking part in this year‘s One-Page RPG Jam. Over 170 contributions already, with 18 days to go!
Personally, I feel a bit lost in the swamp, looking for orientation. If you post a link to your mini-system here, I‘ll take a look and write a few lines.
My own contribution this year is Griffin Riders:
I thought I’d participate, but alas, the end of the jam came faster than I realized it started. 
Your griffin riders write up sounds interesting. Good on you for making something!
Thanks! Yeah, those jams always end sooner than expected.
By the way, there were two more contributions from this forum, even if the announcements ended up in another thread.
Maybe we‘ll make an even stronger showing next year!
