I'm the type of player that enjoys getting immersed in the game. As such, I am a big fan of player housing. The implementation in LotRO was pretty good, but felt like they abandoned it once they had it in place.
I read this write-up today on the direction that the developers of ArcheAge are taking with player housing and absolutely love a lot of these ideas.
Imagine a nice little Gaiscioch community set somewhere in Moonshade Highlands with each of our houses, a great hall and some community trading and crafting halls. Okay, it'd be huge, but still. How cool would that be?
