I loved the Al Bhed!
I didn't like them in the beginning when they kidnapped Yuna but after their lost their entire city to protect Summoners from the Guado ?
I like their gear too. It looks like space suits to me, or something really alien. I think they added a lot of novelty to FFX. And a dark / punk cast to all the sunny tropical scenery
I wish I was smart enough to speak Al Bhed. It seems such a cool code!
