The Witcher 3: Blood and Wine
First off, yes, Blood and Wine is an expansion of 2015’s Game of the Year that released back in May this year. Offering a new, beautiful area to explore, a huge main quest path, a bunch of side quests, Witcher contracts, new armor, and all manner of other features, Blood and Wine was more than your average piece of DLC.
In fact, Blood and Wine is the prime example of how an expansion should be done. It not only managed to change things up ever so slightly thanks to its fairy tale setting of Toussaint, but it provided a good 30+ hours of high-quality content. While other games release smaller bits of DLC at a premium, CD Projekt Red continued to show their love for the fans and offered them one hell of a final journey with Geralt. Developers, take note. This is the way that expansions should be done.
