Soooo first impressions... honestly...as critical as I am of TS4 I am REALLY enjoying this pack. The world is beautiful, the beaches are always alive and populated with townies, the mermaids have some really neat customization options. It doesn't hold a candle to Island Paradise but I've still had a great time playing.
But...I do have to agree with other players (including Game Changers) who have said that it feels more like a game pack than an expansion. Outside of this island world, there really isn't much to expand on the overall Sims experience. And I do really miss houseboats and boating in general being a group activity. The complete and utter laziness of the lounge chairs makes it lose some points for me too.
Overall, this pack is a lot of fun. It is one of the better TS4 expansions (the best still being Get Famous) but still feels kinda...lacking.
This pack should have been a 9 or a 10. But it just feels too much like the poor man's Island Paradise for me to give it anything higher than a 7 and even then I still feel like I'm being generous. There are just sooo many little things that add up and keep it from being perfect (story of TS4's life, at this point). Which makes the fact that it was so close all the more frustrating.
