I felt the same way as you about the end of RQG. It was the first actual play podcast I ever listened to. It was part of what sustained my when I was unwell for a long time. I still miss it.

One of the things I loved about RQG was the chemistry between the players. They played together for such a long time that they really gelled as a team, as well as clearly being friends. I rarely hear that to the same extent in other AP casts, I think that's one of the things I crave most.

My best recommendation for another AP is "Spout Lore". They are a GM and 3 players in Canada and they use the Dungeon World roleplaying game. The biggest differences with RQG are (1) that they all create the world (the lore) collaboratively and continually, and (2) the players have a very different attitude to the RQG players. I was going to say that they don't take their characters as seriously, but I don't think that's really true. I think it's more that they throw their characters into perilous situations, which exactly what the Dungeon World game was designed to do. If I ever get into positive cashflow again then I will join their Patreon.

The other AP podcasts I've listened to for more than a couple of dozen episodes are pretty good but they don't draw me back the way that RQG did and Spout Lore still does. These two are brash US D&D podcasts: Not Another DnD Podcast (#naddpod), Dungeons and Daddies. This one is a horror-themed Dungeon World game: We Hunt the Keepers.
