God this game is so awesome on Vita. Weird how such an old game looks better than most of the modern games made for the system.
Any Blitzball tips for an amateur?
It's the very first game against the Goer's don't worry about trying to score during the first half.
The main thing you should do in Blitzball is hit triangle and change to manual immediately, automated movement sucks.
Using Letty, Jassu, Botta, and Tidus pass the ball between these four on your side of the field. Players earn experience based on actions performed. So the more you pass the ball around the less chances the opposing team has time with the ball the better your odds will be.
Once Tidus is left 3 or higher he can use the Jecht Shot (if you successfully did the mini game on the S.S Winno on the way to Luca)
The Jecht shot will nullify up to one defending player in front of you. So even if you approach the goalkeeper with two defenders blocking you, you can break one of them use the Jecht Shot to blow through the 2nd defender and more often then not score easily.
After the events in Luca you can recruit free agents, I recommend hiring Wedge (Foward), Jumal (Goalkeeper), and Zalitz (Defender) which all three of these people will make a good replacements for Datto, Keepa, and Botta.
The reason why most people are turned away from Blitzball is because your starting team has some of the worst players given you, the only half way decent members you get are Jassu and Letty, everyone else is pretty much easily replaceable with far superior starting stats.
Key things to know when hire free agents. Defenders should have high attack and decent passing stats, Mid fielder (Letty) should also have a reasonable attack and high passing stat.
Fowards job is generally score so a high shot stat is preferable. Keep these things in mind using the handy charts in the link below to build your ultimate blitz team
