Blitzball is an awesome minigame. Yes, it takes quite a bit of tutorial reading and practice to get the hang of it, but it was a fantastic idea for a minigame. The Scouting system gave it a "real sport business" feel, as you can scout and recruit, and pay them salary to bolster your team.

Its only downfall, as already mentioned, is that you have to log so much time playing to get Wakka's Jupiter Sigil. The number of games required to play should have been far less.

Blitzball like Quiditch? More like water polo, played under water, because of the tackling and passing by throwing the ball. Then add in kicking to shoot the ball, and its almost a cross between water polo and soccer (football). Then its like ice hockey with the number of players used (1 centreman who takes the blitzoff which is like a faceoff, 2 wingers, 2 defence and a goalie).

I thought Quiditch was a freakin' ridiculous game , but that's just me. Its kind of stupid that the efforts of the team can be pretty much pointless is the Seeker is successful.
