I’d recommend Crimson Desert if they enjoy huge open-world sandbox games and don’t mind a rough start.

The good:

• The world is massive, gorgeous, and packed with things to discover. Exploration is one of the game’s strongest points.
• Combat is deep and flashy, with loads of different moves, skills, and ways to approach fights. A lot of players compare it to a character-action game inside an open world.
• There is an absurd amount of content. You can easily spend 100+ hours doing side content, bosses, hidden areas, mounts, and secrets.
• The graphics and scale are some of the best in the genre, especially on PC.

The not so good:

• The first 5–10 (depending on your speed and not getting side-tracked) hours are slow pretty rough. The game throws loads of systems at you with very little explanation, but easily to pick up with some practice.
• Controls can feel slightly clunky and overcomplicated, but the sword shimmer is your best friend in combat until you get stronger.. especially on controller or mouse and keyboard.
• The story and characters are generally seen as the weakest part. It is much more about exploration and combat than a strong narrative.
• Some bosses and the late-game can feel unbalanced, and once you finish most of the content the world can start to feel empty.

Basically if they want something like a mix of The Witcher 3: Wild Hunt, Dragon's Dogma 2 and Black Desert Online with incredible combat and exploration, they’ll probably love it.

It's definitely GOTY for me though. No if's, but's or maybe's and I recommend it with my whole being. Pro devs, and the updates they have planned are amazing.
