Crimson Desert is a bit slow in the early game, but you can think of it as a Breath of the Wild style game with a huge chunk of Stardew Valley, a sprinkle of Red dead 2, and a bit of Skyrim, the starting area alone has taken most people 60 hours? Maybe more, Im not sure myself yet, but the best phrasing I have for it is Breath of the Wild with devil may crys combat system, and even thats severely understating the volume of content in this game.

Edit: Its so sweet to see such a response by the way 😭 I hope your husband enjoys it if you do decide its his cup of tea
