We certainly do take topic requests! Overworlds I'm not sure we'd have much to say much about though. I haven't seen *any* where they do more than add a little flavour and sense of breadth to the game. And there are no good examples of procedurally generated overworlds (I'm not even sure they're a good idea). If you have some specific games you think are worth mentioning let me know.
Fair enough. I suppose the games I like with big overworlds are large and static. Tome4, Legerdemain (hugely, hugely underrated game) and ADOM. It's just a soft spot of mine. Probably not much to discuss from a mechanics point of view, but I just can't enjoy a game that takes place entirely in a dungeon that much. I need to feel the ascii suns rays on my face.
Whatever you do, please don't start talking about violence, sexual harassment, and rape like you guys did in episode 57. That was horrible to listen to, it felt like an after school special. I had to stop listening it was so uncomfortable. You might as well have started the whole thing off with "tonight, on a very special episode of roguelike radio". I really, really, really think the show should stay well away from srs real world topics.
(apologies if that criticism seemed over harsh, but i hope you'll take it as intended - something constructive from a person who very much enjoys listening to the show).
