I have just started playing PlaneShift and I think it's great! You are obviously serious (without being obsessive) about role playing. What a welcome relief. It was that, more than anything else, that attracted me to this brave new world. Let me add, however, that the graphics are fabulous, and really cinched the deal.
I am pleased to read that, in the future, you plan to sell dwellings rather than allow players to build. I have seen the chaos that building makes of the landscape - how it ruins the verisimilitude of the game. Stick to your guns on this. As a cheaper option to buying an entire house, perhaps you might allow players to rent/buy rooms in game controlled houses.
I know you have received your fair share (unfair share?) of negative criticism, but I have none. The game is still in development, but even so, it is very enjoyable to play. I look forward to greater things in the future. Well done PS Devs!
