This is an absolute classic shadowrun adventure. It oozes atmosphere and the scenes that are provided are actually quite good and are really on point (from a thematic perspective). At the same time this adventure can be easily reskinned or lifted into another ruleset. There's very little that ties this to the shadowrun universe (there's a dragon but you can change her into a firespitting drone if needed or leave this out entirely). If you're looking for a Cyberpunk RED/2020/2077 adventure this really is a treasure trove.
If you're going to play this "as is" watch out for the plot. There's a huge (back)plot that is very difficult to share with your table. Without this plot it's almost impossible to set up the emotional pay-off that makes a good adventure brilliant. There's about a 99% chance that your table won't get it. If you're a new DM/GM you'll be disappointed in yourself. As a DM/GM you have access to the plot and will wonder why it didn't come together during play. Spoiler-alert: it's not your fault so don't blame yourself. Mercurial relies on a 2+ page piece of written exposition at the start of the book that is hidden and will most likely remain hidden even if your table pokes around for it. To bring the plot forward you need to totally reskin the adventure, provide a plot hand-out, or do the exposition at the table - none of these solutions are ideal. The best solution I have found is to spin out the background story/plot in a seperate one-shot with disposable characters and run it as a session zero or as a pallete cleanser. This won't work at every table and requires a lot of work even for a seasoned DM/GM. Yet with all it's imperfections this is an absolutely brilliant adventure that is absolutly worth to be ran in 2021 (modified) at your table! Also - at it's current price this is an absolute bargain so there's very littly that should stop your from picking this up.
