FFX’s Hidden Affection System
Author: 
September 1, 2009 
Here’s something that I never knew existed in Final Fantasy X: it has a hidden affection Easter Egg built in. I came across this a few weeks ago searching for FFX videos, watching a few of my favorite cut-scenes.
*Mild Spoiler Warning*
It has nothing to do with dating (unless you’re thinking about Yuna, Rikku, and Lulu), but what the “affection system” does is that a character will join you on a snow mobile ride once you get to Mount Gagazet (Kimahri’s home).
Before you get to the event, you need to give the character you want Tidus to ride with a potion (or another healing item) while in battle prior to the cut-scene.
It’s not just for Y/R/L… It can be done with Wakka, Kimahri, and Auron—as seen below.

This is pretty old, it was mentioned in the FAQ, but not exactly something so detailed that I was told there was actually a hidden affection system. I only ever managed to get Lulu anyway, I think.

Yes, almost a decade old, but I’d thought I share this lol. ^^
I didn’t know this was possible because the fact that I got Auron the first time because I thought it was meant to happen either way in the story.
When I played FFX the first time, I avoided reading the guides (except for the mini-games lol ^^; ).
