Eh, a lot of people love to talk for "the fans" trying to descrive FFXIII as an untold horror, but fact is that quite a lot of people liked it. You don't sell 3 million copies of a sequel if "the fans" didn't like the original. Some fans did, some didn't.
Was it the best Final Fantasy ever? Not at all. Was it as terrible for "the fans" as many try to paint it? Not one bit.
And I personally didn't like it much, but I don't talk for "the fans".
