Technically my first exposure was the cartoon, but now I think about it I don't think that ever made it clear that there even was a game.

Absolutely! Do you have a recommendation for a solo hack of AW?
I understand your situation, but my first recommendation would be to take another look at "that online stuff" - some groups are very supportive for beginners, some ways of playing (e.g. pbp) are easier if you are still learning and/or find playing over video/audio too stressful, or don't have much time, etc. The social element and collective creativity of playing in a group is part of what makes RPGs fun.
However, there are hacks for solo play for several great systems. For Blades in the Dark (the system I'm currently playing most) both Alone In The Dark (https://www.drivethrurpg.com/m/product/282013) and Omens in the Dark (https://guimonocores.itch.io/omens-in-the-dark) have been recommended to me, and the BitD Discord server is very friendly if you have any questions.
It's kind of alternate Victorian postapocalyptic with ghosts, but you can customise the setting however you and your players want. It's relatively simple rules-wise so definitely worth a try.
