The fact that it's all shiny and new right now may be affecting me a little bit, but I am loving Lucky Palms so much. The world itself is visually stunning and the prebuilt houses are gorgeous. The only thing it misses out on is the "cozy" or "home-y" feel of some of the other worlds, but I'm pretty sure that's intentional. It's definitely my favorite world, at least right now.
If I were to get over my Lucky Palms-obsession eventually, I would probably go back to loving Riverview or Bridgeport the most. Bridgeport especially stands out because it's completely different from everything else. Sunset Valley and Hidden Springs are also pretty great. Barnacle Bay, Appaloosa Plains and Starlight Shores are not particularly memorable to me. I've played in all of them, but I have no idea what they look like, and when it comes to generic and "vanilla" worlds, Sunset Valley and Riverview are just much more interesting. I didn't buy Lunar Lakes because the atmosphere was too sci-fi for my taste. I like natural.
As for Twinbrook, I never really cared much for it. Then again, I haven't played it much, but I kind of disliked the swamp area. The world seemed to veer into a darker, edgier, dirtier territory whereas I was expecting something more Riverview-esque. Maybe I should give it another shot if I feel like playing in that kind of atmosphere. I'm assuming Moonlight Falls will be pretty dark as well, but this time I'll be ready for it.
For the record, Shang Simla and Al Simhara would both be way ahead of the rest for me if WA worlds were playable in the same way.
