Not at all; 's my favourite Final Fantasy over all as well. I've got particular favourites like VIII's setting and IX's feel for instance, but XIII was the first one genuinely resonated with me. I think it's because it's got more complete and fleshed out character arcs than the average FF-game tends to have; I've always been sensitive to that sort of thing. That and I love the way they made the normally ludicrous power levels Final Fantasy characters end up demonstrating make sense through the L'cie concept, and made it a central part of the story.
Sorry, as for the point of your thread.. I do fear you mightn't hold out too much hope. As others have said, perhaps with the PC release of the most recent XIII game .. but it's my suspicion that if we're going to ever see a way to acquire that kit again, it'll likely be via the optional services/cash shop.
