I'm pretty sure Tasos won't be removing any of our "freedom" from Darkfall. AV is adding in more incentives for PvP and politics, so they are not forgetting about the sandbox. What the game has really lacked since day 1 are sandbox tools. Their last attempt were funhulks; we all know how great those things are, lol. Hopefully, they'll be improving on this in DF2.0. All they really have to do is add in random crap into the world and then observe how players will use them, or watch how it will affect the game world. They need to start playing around with these things a little bit more.
Along with the tools, DF1.0 didn't have anything else to do besides PvP. This was the biggest flaw in its sandbox. It allowed the freedom, but it didn't give that many options for people that wanted to do other jobs besides fighting other players. After watching this interview, I'm not so sure anymore if they will ever remedy this. Tasos has said he wanted it to be an MMORPG with an FPS feel in an open "sandbox" world. This just screams out PvP, PvP, and more PvP. It isn't a true sandbox MMORPG if it doesn't allow people to do other tasks without being forced to PvP just to truly enjoy the game. Players need to have more options to play Darkfall for this game to attract a larger audience. I think this is the key for a very successful Darkfall 2.0.
A sandbox world is ran by the players. The people will need incentives to do things and tools to work with along with the freedom to be whatever in an open world.
