Ugh I hate the chocobo race you have to get 0:00 on to get Tidus' weapon. I played if for 2 hours last night and I got 3 seconds like four times and even got 1 second with 12 balloons and 0 birds and thought I had it. I wanted to throw my Vita into the wall. This shit is just too luck based. My one complaint from this game really...
Funny enough, I find that's the easiest one of the painful ones.
Butterfly, lightning dodge and anything Wakka is way worst for me.
Also, in my second playthrough I got 00:00:00 EXACTLY and it did give me the crest/sigil.
Most FAQs say you have to score under 0, so I was sweating beads, fists clenched awaiting the game's decision.
