ohhhh man. my favorite genre of podcasts is audio dramas, they make up the biggest chunks of what i listen to at work. and if you love bright sessions then you have very good taste.
a lot of my recs have been mentioned already - friends at the table, the adventure zone, alice isn’t dead, penumbra podcast, etc. etc. so i’ll just mention some i haven’t seen here yet!
ars paradoxica: you might have already heard of this depending on how far into the bright sessions you are, since there’s a crossover episode between the two at one point. it’s a sci-fi show about unconventional time travel. i had a hard time getting into it because sci-fi isn’t my favorite, and it takes a while to build, but it gets good. queer and POC characters involved, too, and not just in a tacked on way, which i appreciated.
the orbiting human circus (of the air): part of the night vale presents network, so you know it’s good. the first season just wrapped up so it’s a good time to catch up! the main character is queer, although romance is not involved in the story. this show is awe-inspiring and heart-wrenching and can get pretty meta at times? also the setting is the Eiffel tower.
