Q: Roughly how much will housing cost including the furnishings and interior designs?
A: I think that maybe 4-5 players, each with one level 50 class could probably buy a house if they put all of their earnings together.
From there it will be possible to buy more land and rebuild, things like that. There will be lots of things you can do like have the roof changed to a different style, and then paint it whatever color you want.
Gaming is supposed to be enjoyable, we are all here to have fun and relax after work. I don't want to have to sit and farm 8 hours a day for the next 3 months just to get a FC house. The price is Sadly out of reach for most players and has disappointed a very large part of the community who were mostly looking forward to the housing feature in this game.
