So, you want to show off the goods Trophies, crystals, weapons, rugs, furniture, and so on and so forth. If you want Star Wars Galaxies style housing, I would count it out. That requires a lot of empty space, and lots of loading time, a lot of people, including myself, enjoyed the Star Wars Galaxies style housing. It leads to a very large amount of immersion, being able to invite players into your own home, and "Show off" what you have, but at the same time, leads to complete clutter and misplaced items, and a very heavy lag spike in your home.
So the choices, if implemented, will be instanced, or open world. So you have EverQuest 2, or Star Wars Galaxies. The instancing option is not a bad idea, but it takes away the immersion. No one visited my home in EQ2 when I put my time and effort into creating it and making it organized and friendly, because no one had a reason to visit my instanced home. While in SWG I had three homes next to each other, with different merchants in each. So players were forced to go into them to buy my cheap goods. And being able to see who entered and when, it was a great pay off, because my time was well spent, and I often received comments on my homes. But having an open world with housing being able to be placed anywhere, leads to unorganized everything, and not to mention it also requires a Sandbox Environment.
So my question to you, would you, if given the option, like to see Open World, or Instanced, or maybe RESIDENTIAL area housing?
