LitRPGs are stories heavily inspired by videogames. Most are pretty 'crunchy', in that character statistics are listed and important to the story etc. Mine is definitely on the softer side. It uses the usual tropes of people being transported to a virtual world, but without the numbers-heavy approach a lot of readers crave - which is one of the main criticisms in the reviews.
So I guess it could be a relatively gentle jumping-in point if the genre sounds like something you'd be interested in :)
There's Unlucky Dead as well. Pretty good first book from the author. I liked it anyway.
