The Way of Kings (Stormlight Archive) - Brandon Sanderson
When I first bought it, I got through about 3 chapters and then shelved it. A couple of years later I was looking for something to read, I saw this book being praised and remembered I had a copy. I ended up getting hooked and sucked into the cosmere.
Outriders was such a disappointment. It had a good amount of marketing put into it, was clearly meant to be a gaas, but fell flat on its face pretty quickly and even released a DLC content update very shortly after release, and was then abandoned.
But so many other good games on that list!
