Ages ago, there was a server emulation project for Final Fantasy XI. The coding got hit with a cease & desist, unfortunately, and to the best of my knowledge there is no actual way to host a rogue server for the game right now. Which is a bit of a shame because it’d be fun to do… even if a lot of the changes I would have liked to see in the game are things that, well, have actually happened over the years.
This may well be me as an outlier, but when it comes to the very concept of rogue servers I tend to prefer less recreation and more using the parts to make something wildly different than the actual game. But let’s put that to a question. Regardless of the technical practicality of it, would you ever consider hosting a rogue server for an MMO? Would it be a recreation of a bygone era of the game’s development, a very different game based on the same foundations, or somewhere in between? And if you would, what’s currently preventing you from doing so?
