Being a huge sucker for Mermaids I'll give credit where credit it's due: In The Sims 4, unlike The Sims 3, you can actually create Mermaids in CAS, the designs of tails and upper parts are much better and the way they swim it's much cuter and well designed.
However, I do feel like they were an afterthought in the expansion pack... cause you can't really get them to do anything relevant, unlike in Vampires. And they could have had so much fun with it. I just wish they come up with an expansion pack only about Mermaids, with a fully underwater world with building mods designed after underwater things. It would be super cool if they researched on merfolk lore (which is huge!) and added more of that into the gameplay and make actions like "mermaid's kiss" for example make the sim that you kiss fall in love with you? It's kind of what mermaids do... have like interactions with pirates and/or with more marine creatures?... I would happily pay for a game like that! And, considering how little representation Mermaids have in video games, other gamers in love with these creatures would too!
