Rift on the other hand is going pretty big on implementing this idea into their game, they announced 'Dimensions' for their upcoming expansion. This feature lets players not only just place furniture inside of a house, it let's them acquire pieces of land found in the overworld, or even inside of a dungeon you've been to previously. As you progress you can acquire more dimensions to play and build inside. They don't just give you a house, they let you make the house, and everything in between. You can also invite or visit other players dimensions and all that jazz. Check out the promo vid here!
I can't express how awesome this is, I can only wish Blizzard would be as ballsy and go all out on a feature like this. Imagine the roleplaying possibilities, all of the customization... you could basically create scenarios inside of a dimension to progress a guild story line, etc. etc.!
Now, a downside that Blizzard likes to bring up is 'it takes players out of the cities.' and whatnot. Personally I just don't think that will be the case if you keep auctions/vendors inside the cities like they are now, there will always be people out there and not just holed up in their housing.
What are you guys' opinions? Pros, cons, would you like to see something like this implemented? I'm curious!
