Let's expand upon this a bit, shall we?
First Legendary caught:
Giratina
Favorite City:
Sootopolis City. It's like Minas Tirith, only better in almost every.
Favorite Gym Leader:
Norman. Nothing feels better than beating your old man.
Favorite Elite Four:
Wikstrom. Lance may have been a dragon master, Bertha might have been with Prof. Oak, and Koga might have been a Ninja, but this dude's a fucking Knight. I'm a sucker for seeing Japanese devs emulating western ideas.
Favorite Criminal Gang:
Team Aqua. While I love Team Plasma's costume design and ideals, Team Aqua at least realizes when they've fucked up royally.
Favorite Crime Boss:
Tied between Ghetsis and Archie; Archie was easily my favorite character in ORAS, purely because he's just so happy to see you most of the time. I'd totally hit a dive bar with Archie.
Ghetsis, though? Dude's a legit sociopath, I applaud Nintendo and Game Freak for going out of their way to make one as fully realized as him.
Favorite Rival:
Wally (ORAS version). This guy had me from Petalburg onward, and that final battle, as noted in
>>24982583, was hype as balls.
Favorite Champion:
Tie between Steven and Cynthia. I wanna see these two duke it out before I side with either of them.
Any other ones I should list?
