When I only owned a handful of games and my RPG purchases were few and far between I was a completionist. I've probably dropped a 1000 hours total into FFX. Because I've played it like ten times through. I have a 200+ save file from FFX and I even got so bored that I played through walking everywhere in the game not running.

I've 100% FFVII-FFX and played each like 5 to 10 times a piece. I've nearly memorized where everything is in FFIX since I've played it so many times. I've played FFX enough that I could tell which monsters would be in a battle be just know the camera angle, since ever camera angle seemed to have different monsters and it was a consistent thing.

I've even 100% most of Xenosage I-III, Kingdom Hearts I-II and Dark Cloud. Unfortunately, around the time I got Xenosaga III I started getting RPGs like every month, there was a 6 month period where there was a new RPG every month and I would beat it and move on. Now I have over a 100 RPGs and not enough time to even play them. So I don't really have the time to be getting 100%.

Though I'm actually on my way to 100% Cross Edge because I was wanting the perfect ending and 100% could be done at the same time. But I really enjoyed Cross Edge enough to play it a second time immediately.
