I wish you the best of luck in your spiritual journey, but the idea of getting a definitive answer to the God question is something humans have been working on for thousands of years. I wouldn't beat yourself up about not having one lol
Jorphdan (the ph is silent) has dozens of videos exploring the lore of the Dungeons and Dragons multiverse. Those worlds have been the setting for enough videogames that I think it applies.
You might also check out Eckhart's Ladder. He focuses primarily on Star Wars but with some digressions into Halo and other science fiction universes.
One of my personal favorite gaming essayists is Grim Beard, though his particular style may or may not gel with you. His videos are generally about a single game and often encompass a game's conception, development, gameplay, reception, and legacy. It's not exactly a lore channel, per se, but I feel like it might be in the ballpark of what you're looking for.
Big ups for Underrail. I'm about 10 hours into my first playthrough and having a blast. I'm concerned I'm going to hit a wall at some point because I didn't really come into the game with a build in mind, so I'm pretty far from optimized. This far though, I've managed to scrape by on luck and buffs, but like you said, it keeps you on the edge.
