Even when I play that game on ePSXe (using the discs I own, BTW) and slowing the game to 1/5 it's speed, I still mess up 3/4 times.
The thing about it is it's not significant if you fail. You can still get a moonstone later and gil is still as free as it was before. It's just a nice jump start to get it all at once like that.
I bet that you think it's not as bad as the first Blitzball game in FFX, right?
I think it's infinitely superior to Blitzball in lots of ways:
1. It's physically (and biologically) possible for two people to be doing this.
2. The music is fun and catchy
3. You don't have to do it more than you want
3a. When you're done you're done and no one ever brings it up again.
4. It's actually fun for someone not playing to watch (maybe for the first two to three times)
5. YOU DON'T HAVE TO DO IT 50 TIMES TO GET THE BEST SETUP!!! (especially this)
6. You don't miss anything in the game by not getting perfect at it (although you miss out on a rare moonstone)
7. Seven's a cool number
8. I don't have to manage a team
9. It's not a game-in-a-game mini-game.
10. It's not sports-related
..... The list goes on. Trust me.
