Possibility to open FFXIV up to a moddable UI? - Page 7
Interesting. I'm very wary of how far they will allow mods to go, though. I don't like the idea (and it seems most people don't, luckily) of allowing for people to get all sorts of weird things done that basically tell you things that the existing game does not already (there is mention of mods that tell you when to cast what spell etc. depending on what a monster is about to do, something like that).
Of course, for now the general feeling is that this will be for skinning only and not for anything such as that. So yay?
