EQ:N looks like a big case of "halfsies". You can build, but only in your own plot. Things are destructible, but not really. The world will change, like mob spawns etc.. but balancing that and making it non-annoying is probably beyond Sony to pull off.

Big draw for the game will probably be questing for tiles, items, etc that enable you to build your home plot up.
