Some years ago now, I ran a few games of Delta Green for the guys I work with, and still have the notes lying around the house. When my current GM said he was going on vacation, I volunteered to run the remaining players through the Delta Green game.
I transferred my notes to LaTeX, padded them out a bit, and smoothed over some of the problems I remember having the first time through.
The copy of Dungeon Crawl Classics sitting on my shelf had a thick layer of dust and a spot where I used the book to smash a bug some time ago. DCC sits firmly in the “old school renaissance” family of TTRPGs. Without going into the hair-splitting arguments people have in the movement, OSR is about playing DnD like it was played in the halcyon days. Before WotC bought it out, before Pathfinder, way back when.
The current hotness in the OSR world is a game called Shadowdark; the publisher had a second very successful Kickstarter just a couple months ago. I grabbed a copy of the core rule and started chatting with folks on the official Discord. My DnD group doesn’t get to meet enough to try a ton of new games- I’ve had to take my Shadowdark gaming online, and have been running on Foundry.
It’s a ton of fun. Shadowdark has been written about and reviewed a number of times, so I’ll not rehash it here. It is certainly a much faster game than 5E. That speed means you can get through more adventure in the same amount of time, which translates to more fun. Character creation and customization options are much slimmer than DnD, but they are evocative. Randomization in character advancement means each hero will become unique as the game progresses.
We ran through my Delta Green scenario last Saturday and finished all the material I had previously written. We’re meeting again this weekend. I still don’t quite know what’s going to happen with the plot; it’s much harder to write for than DnD in my opinion. You can’t exactly just plop down a dungeon and tell them the loot is at the end of the maze.
