I am not that deep in Tolkien myself (have only read two of the books tbh) but that quote of his about cordially disliking allegory just sprang to mind. :') But yeah, that universe is certainly its own can of worms.

It has been a while since I revisited Fallout myself, mostly because I've fallen down a Dragon Age hole I show no signs of climbing out of anytime soon. :P And then I really need to play The Outer Worlds... and the half dozen other games friends have been after me to play!
