This idea is rather usual to many other games. To have your own house.
I know why some people don't like it, but it would be kind of awesome, right?
Then you have a house you can go to with your friends, and maybe some nice features to it!
It would be a time-killer if I'm bored and just feel like decoration my rooms etc.
I haven't thought of any more stuff you can do with or in the house since I recently got to think about this!
If I get more time to think I'll write down everything I come up with. And if you also have something you would like to add, please post a reply!
..Isn't what you're describing a guild hall?
