I played DFO, and for what it's worth, I think it's a fantastic game. I'd like it if Aeria could pick up the rights too (we license Shaiya, whose developer is now owned by Nexon, so we do have some points of contact). That said, there are some things to consider before that could happen, like consideration of where it would fit in our schedule of upcoming work and releases, as well as the licensing cost Nexon would want for it (which would probably be on the higher end, as it's very popular in Asia).
Still, I think we could do a lot worse than adding as finely-made a game as DFO to our portfolio. If anyone asks my opinion of the game, I'd go to bat for it.
