So DF Whiterock ended a short time ago. You can see the announcement here:
The Premature End of DF Whiterock
I'm a big fan of postmortem reports on game - what went wrong, and what went right. It helps me, as a GM and a player.
Here is the post of what went right:
What went right in DF Whiterock
It's a mix of what went well for the PCs (tactics and cooperation that worked, for example) and what went right for the GM.
I've written a lot of posts about how I'd do things differently. Here are three:
Megadungeon Reflection: What I'd do differently in my megadungeon (1/2014)
Felltower Reflections: 5 years later (10/2019)
More Stuff I'd Do Differently in GURPS DF Felltower (4/2020)
Those two posts are good stuff.
