Well over a hundred hours of content. Incredible world-building, compelling story, great characters, deep gameplay mechanics, fantastic voice acting, amazingly detailed world design and just overall super immersive, everything you could ever want from a RPG experience and then some. It's no wonder the game is heralded as one of the best of all time, it's certainly one of my favorites.

P.S. Gwent is one of the most fun and addictive mini-games in an RPG since Blitzball, you can easily spend hours just playing it alone.
