I'm not ready to rate it yet but I'm thinking around a 7. I moved a sim into a lot, turned her into a mermaid. The island is stunningly gorgeous, and the animations are beautiful and so fluid (pun intended). It's very immersive and relaxing. I like the odd job system too. YET... I would agree there seems to be a lack of gameplay. I haven't played the conservation career yet, so that might change my mind one way or the other.
But I'm missing challenge: there are no new skills and no new whims. Outside of the conservation career, there is no sense of "progression."
Starting to really think that the game really REALLY needs some overhaul in terms of whims, aspirations, and personality. More depth, not just water... PLEASE!!!!
