Aaron took an initial, magnificent idea and was able to run with it very, very well! However, I think the earlier episodes of this podcast - perhaps the first 300 - are better than the latter ones. I think this is perhaps because, in the end, there is only so much real material and not only has Aaron plumbed that well for this podcast, but he's tried to branch out into other similar areas as well.
Lore is ABSOLUTELY worth a look, and probably the first podcast that I went through all the back catalog of. Start at the beginning. You won't be disappointed.
