Ah! Another fan of beloved franco-belgian comics! Tintin and Blake and Mortimer were the main inspirations for Enigma, and although it morphed into more than just a Tintin ttrpg, it still holds onto those roots. Dastardly villains, comic relief, heroes who always seem to see it through to the end.
Obviously appendix-n is a little different from the era of Tintin, but there were some weird Blake and Mortimer adventures where they go to Atlantis, the future, etc so I felt like I could make it fit. Thank you for the kind words, hope you get to try out Enigma!
