Yeah, I agree that the marketing was off. It does feel like they planned more at some stage that didn't make it into the pack (Sulani culture, mermaids, one of the maps is named something that implies that resorts were planned at one stage), but what they have... I love that it's not, you know, WASPy North America. I love that the Welcome Wagon an the neighbors are different. I do love mermaids and play mermaids a lot, but I also harp on their tombstones and bassinets and lack of skill tree.
BUT. I love that you can change Mua Pe'lam with gameplay, and feel like Island Living introduced a lot of features that were expanded on in Eco Lifestyle (another pack I like a lot and use a lot and bought for my off-grid mermaids). The active career is great, and I've copied you, @PipMenace, and bought Caldera Camp as a "business" (one of my conservationists is rich) and then I made a club and have my Conservationists have "club meetings" when they go to work, so they see their coworkers. I use the club "together" whenever a work action has that option, so they're all taking samples from the ocean together, etc.
I do, however, have to UI cheat away the WFH task "go snorkeling" for my mermaid Conservationist still...
