It's okay. If you played the first two installments, don't expect it to be like that, like I did. There's customizing, but it's just your suit, stickers, emotes, etc.
The story is okay, nothing exciting, and the missions are short. You can't surface, and you never are without a suit. It's not as in depth or rich in it's gameplay, scenarios, animations, and story, and the soundtrack is decent at best.
I still enjoy it, and it's a relaxing game, and I do like that they included some of the creatures and lore from the last games. It's just not the same, and I'm a little disappointed about that. Hopefully we get a new game that takes all of this into consideration.
