The 3.5 years between XII-XIII is exactly my point. You liked 12, you didn't like 13, their record for the past two games therefore is good - can't expect everyone to like every game they put out, but it seems bad, because the wait for XIII was so bad.

X was also hailed very well, and where you may have disliked it, it has a huge following (myself included). FFXI was a very successful MMO, if you don't like MMO's that's preference. I'm not going to call Final Fantasy a "sunk" franchise because of a mediocre performance with 13.
