Hmm, because it's a Turn based combat rpg I don't have any need for using a controller on pc game !
So for me: no demand .
But even with a real time combat rpg like DD and BD I don't have the feeling I "need" a controller ...
For me:
all of D:OS is PC operating (with mouse and keyboard)
OR
BOTH : full pc game + full console game
And nothing in between !
But again: this kind of game is best played on a pc, especially with the "editor" in mind !
