I love X, and still play it a ton.
Loves for X:

Wakka - Never understood why people don't like him ya? In the beginning he seems a little spaced and stubborn yet as his story unfolds you see what drove him to that. When his brother died and they way he died you see he was looking for information and his place in Spira. He went to the natural path of religion to try and find answers and make sense of everything. Plus he is a power house in battle so like um ya. He kicks Aurons but like nothing end game.

Blitzball - Teach us how to Blitz! I loved Blitzball and it was my favourite mini game of the series. The Aurochs are not so great at the beginning but a few of them turn into something great if you just take some time. For instance Datto is the fastest Blitz Player in the game, he has a good shot, and I always keep him on my squad. Datto is a MVP that breaks the game if people keep him on the team. Plus even with all the original Aurochs I still end up winning and rolling through teams. The only replacement I use is Letty for either Brother or Wakka.
