This is overall a great Collector's Edition and all the items and goodies included were great and very high quality. And in case you're wondering... Yes, it does include the game.
The artbook was gorgeous, thicc and filled with tons of pictures and concepts about the world and its characters. The steelbook is beautiful and makes the game feel premium and unique, besides it looks great when displaying it on your shelf/collection. Finally the coloured cards and the poster are cool add-ons to have to round up this edition.
The one thing I truly missed was not having the soundtrack of the game but aside from that everything else was outstanding.
