World of Warcraft's player housing has been in early access for some time, and players are already building star destroyers—that's because Blizzard's leant more towards the freeform side of things, allowing home decorators to scale, rotate, and freely clip objects into each other to their heart's content.
I got to speak to design director Maria Hamilton recently, who said she's been wowed by the tools themselves: "I think the first thing that I said on seeing where they were really early on was 'Oh my god, I want those tools', because they are vastly better than what many designers are using for building out areas."
