I don't know how to rate this, given that I've never rated anything here on DriveThru. The system is odd. Bad to Good on a scale of 1 to 5 . . . The Demonplague is pretty good, so without firm conviction I give it a 5?
I'm currently running this for a group of 3 and you can follow our progress here: https://thebusybasilisk.wordpress.com/2018/11/29/lemons-and-lemonade-or-heroes-of-luna-valley-session-1/
One of the creators, James Intracuso, is running it on Twitch as well and it's going to YouTube on the Don't Split the Podcast channel.
It's “a clever mix of classic D&D adventure, sandbox, and hexcrawl in a post-apocalyptic setting you can easily drop into your world” to quote the Kickstarter, which I backed because Johnn Four.
It opens in a town, which has a world-threatening story, several intown crises, a map and a bunch of NPCs with quests, secrets and problems. There's nothing not to like, really.
The adventure is cut into managable sections and the PC's are coaxed to go rescue goods and people from two locations and make friends, enemies and gather knowledge before heading out to the 3rd to confront a necromancer who experiments on the living for the greater good.
And that's just the first part of four.
Part 2 is a continuation, where choices and outcomes of part 1 affect the changing face of the valley the PC's live and adventure in. It's a 4 part (?) McGuffin hunt that takes you to some neat places.
So far so good . . . Part 3 is where the oddness starts. As written, it's an exploratory hexcrawl full of random tables and encounters. Every so often, you're instructed to runa a particular encounter and level your PCs. I will start using this portion as soon as I run out of cool random encounters from part 1.
Part 4 is a dungeon crawl to reach the BBEG. The dungeon is coolish, but not amazing. I'm hoping that between the beginning and the end I get enough awesomeness to include at the finale.
So why this instead of some other adventure? Education, maybe? The first 2 parts are pretty great world-building around the PCs. Part 3 is more randomness than I've ever used and looks like fun. And I'm just hoping that part 4 doesn't let me down. Combat and dungeon crawling will never be my favorite part of the game, so maybe I'm biased and you should ignore me. Cool people and places? That's my favorite part! Interaction with the world and its inhabitants. Here, Demonplague shines pretty brightly and that's why I'm running it.
If you're on the fence, do check out James' game, which is easily searchable on YouTube under Demonplague. That will tell you what you need to know:)
Another selling point for me is 5e (an easy system to run and play) and the brevity. Your PC's level rapdily and I expect to finish this well within a year, which, for a campaign, is pretty good.
