Mine was a battle against a rival gang (we are working with them for backstory reasons), they had a manticore and we are level 3 so it was intense. Most of us finished with 2 or so hp! But looking forward to finally be level 4 after a year.
Assuming you’re being hyperbolic at the end there - the samey, no-actual-options feeling of DND is what drove me to Pathfinder 2e. And all the rules are officially free here.
But if you weren’t being hyperbolic and want something in the same fantasy-action genre: Genesys is pretty awesome.
If you want something really real off-the-wall and different, try the one-shot friendly slapstick-comedy The Sorcerer Supreme (also free).
I’ve thought about Pathfinder 2e. I really intensely disliked pathfinder 1e so I didn’t even consider it for a long time. It sounds like they changed a lot though.
If I go back to a fantasy dnd-like it might have to be Pathfinder, but I worry about how so many players can barely learn a simple game trying a complicated one. And unleashing my inner power gamer I tried to banish after college.
I really want to try Fate, but finding non DND players is hard.
