Remember reading the WN for this and for whatever reason getting a buncha rec's for streamer dungeon type novels. At least I think this was it. There were a few. Anyways I find the concept cool especially the ones where they end up doing guides for other people. The ones where the dude has a tamed strong/cute monster are fun reads too.
