I have to agree with Samoth on the idea that this world could have been better. I really like the Sci-Fi theme, so it was a good news when EA announced they were designing such a world. I've personally never been a fan of EA pre-made buildings and Sims, so what I'm looking at is rather how the world itself is done (CAW work) and the new objects that come with it.
What I found good in the preview is all the more natural areas of the world, the big craters for instance. They seem really finely sculpted and painted. What I find less interesting is the big flat sandy zone in the middle. It just looks very bland to me. I understand they want a large flat area, it's much better for lot placement and routing, so it's a sensible decision. But, it could still have been painted in a more interesting and good looking fashion.
I'm not convinced by the super mega huge spaceship, I expect players will experience uncomfortable camera movements around it (think about the huge high-rise structures in Bridgepoort). And I'm very disappointed by the portals Rabbit Holes. This world was a unique opportunity to design really nice looking futuristic RH, and I feel they just missed that chance. Since EA has never released a Create-Your-Rabbit-Holes tool (and this is still one of my fool dream with the Sims 3 :-), we have no other choice but to depend on what they offer (sell) us. And well, big bluish doors are not good enough for me.
This world seems also a bit lacking in additional content. The fancy trees, new window(s) and wallpapers all came with a patch, so even if they are nice, they're not new anymore, nor specific to this set. The big blue crystals are not overly appealing either, and I'm not sure there is much more stuff besides a few world items (which might not even be enabled in CAW).
So, I'm not going to buy it I think. If I wanted to buy an EA world, which is not really needed when they are many others as nicely done and free, this is the one I would get for sure. (Barnacle Bay and Hidden Spring never interested me the slightest.) But I'll certainly wait for a really nice sale because at 2400 pts, it's not worth it for me.
So, it's not a complaint indeed, more a general disappointment with the stuff they release, this world being no exception. They have everything to do really great content with long lasting gameplay. And my feeling is that EA is too often and too easily satisfied with very average design. They could invest a little bit more of the huge cash they earn in their products.
