I picked Blitzball. It was one of my favorite aspects of FFX. I played FFX a lot more building up my Blitz team. Ten was so short, but I liked the game and I felt Blitz was a fun game.

Tetra Master did rock, so did Triple Triad. But I played blitz more than I played those other ones so, I chose that one.

The FFX-2 Coin game sucked. It was confusing and virtually pointless (only to get a certain something from Shinra was the game useful)
