Did some work on my own turn of the 20th century wilderness survival horror game this week. Including writing an overnighter (one shot) that takes place in an Adirondack great camp. It uses my own ⚡thunder20⚡ rules system.

Heck yeah!

⚡thunder20⚡ encourages players to describe their actions in a way that both makes sense for the task at hand and the Stat they wish to use. This, I hope, leads to more depth to their roleplaying and encourages GMs to award Advantage!
FRPG GM Tip: Giving players advantage on rolls is one of the best ways to reward and encourage roleplaying and out-of-the box thinking. Whether it’s a fervent speech at court before a Persuasion check or leaping off a balcony before a final strike, look to reward each player this way every session.

After being steeped in D&D combat for decades, I'm wrestling with the challenge of intentionally designing adventures that do not assume combat in every scene/encounter...

⚡thunder20⚡ is a roll-under-your-Stat resolution system so "statblocks" can be much simpler:
