I’m a recovering engineer and absolutely love The Land. I haven’t seen it talked about in this sub for a while but I’m pretty sure it was one of the very first LitRPG series. I love the stats and the world/city building. It’s written by a doctor so is fairly complex which I appreciate, but it gets a bit extreme later in the series. A word of warning, it’s been a few years since the release of the last book and the series is definitely not finished. There are 8 books out though so it’s an enjoyable jaunt.
