I don't know what other people think about it, but I would guess most people hate it? A mini game in an FF should be something easy to pick up, it should be fast, and fun. I tried blitzball like, twice, and I just didn't get it- and it didn't seem potentially fun enough for me to actually go through the boredom of learning how to play it well. It was a good idea, different from the card games, that's for sure, but I was just incredibly bored while playing it.
