I liked Blitzball. Jecht Shot Mark III FTW.
I feel you guys on finding the sigils n **** though.
I only ever bothered with Wakka and Yuna's before saying nope.
Auron's is pretty easy. His crest is in the dead end of the Old Road (Mi'hen Highroad.) His sigil only involves getting enough monsters captured to do either 10 area creations or 10 original creations. For an area creation, you only need one of each monster for that area. You get it from the arena master the same you would Yuna's sigil.
Rikku isn't too bad, with a walkthrough and No Encounters equipped. Her sigil is easy; just look for a chest on the east side in the western Biknel desert. Her crest involves running around the area looking for cactuars for the prayer stone in the western desert (just above the sandstorm.) You get little clues and find out where they are. You play Red Light Green Light with them, but it doesn't matter if you catch them directly or not. You still get credit. You don't even need to leave the island, except for one of them and he's on the deck of the airship.
I almost ranted earlier because my PS4 plug had a small arc when I plugged it into the surge protector and wouldn't turn on. It turned out that neither me nor Sasquatch could figure out how old the surge protector was, and he had a backup APC/PC 600 watt that wasn't being used in the house. Works fine now.
I should known how much Murphy was gonna love me yesterday when I woke up after 3 hours of sleep and put my foot into an empty soda box.
