The game is an MMORPG. massively multiplayer online roleplaying game.
The role playing comes from customizing and choosing a class, taking a specialization, upgrading your stats, leveling up, taking a profession etc etc.
Player housing, if done right is the ultimate roleplay feature, Blizzard stated something and when they did it they were 100% right.
They don’t want player housing to feel silly.
Simply putting a hut and the ability to place some chairs here and there won’t cut it.
They need to make the player housing something involved with the player, a long term project and something the player can keep adding and interacting with.
Take for example garrisons, garrisons SUCKED. because after an initial woah and a couple of days playing table simulator, people got bored.
A player housing is ( to me ) something that an RPG game really needs, and something that should affect, reflect and correlate with what you do.
Be it having friend npcs, rare visitors, pet place, placing guards, farming rare decorations, farming building parts, growing your own crops near, setting a profession hub, enjoying the scenery, showing friends what you’ve done and much much more.
So Tl;dr : player housing is the ultimate RPG experience and a pretty fun if done correctly aspect of the game that can serve as it’s own never ending content.
