Any episode where they talk about Destiny is going to be a moan heavy episode. They have such a weird love/hate relationship with that game, especially Jeff as he keeps declaring he wont go back to it then just gets sucked back in lol.
I think as a whole they like most types of games, apart from maybe JRPGs but Jason is the closest to being a fan of those when he makes an appearance on the bombcast. I think they do moan a lot but it'll just take one game they all love to turn that around. Like the Witcher 3 discussion this week, they did explain the flaws of that game but by the end Brad and Dan were still absolutely in love with it.
The random stuff is excellent yeah. Its probably one of those things that can be a bit off putting at the beginning as you have no context for anything and dont understand who these people are but once you are a few episodes in it all just kind of clicks. Like knowing Dan is basically a man-child who has all these weird stories.
I've probably mentioned it before but I recommend watching some of the "Best of the Bombcast" videos on Youtube. Its just a load of the best clips and you can lose an entire weekend really easily listening to it.
Here's a link to one of the playlists (think I might listen again myself actually)
