Oiy...
Despite how much love I give to FFXII, I've only beaten it once and I never have been able to finish a second playthrough cause something always comes up. FFII is also in the same boat, though my last playthrough is saved before the Jade Passage (second to last dungeon in the game for those who don't know) whereas in FFXII I just finished the Sandsea.
Despite how much criticism I give it, I think its safe to say that VII is my second most played FF title. On that note, I always struggle to play through the game after leaving Midgard and I really have a hard time getting through the second disc for various reasons.
Even though IX is my favorite of the PS1 titles, I've played it the least amount of times.
I have a really hard time playing through FFTactics (or the FFTA series) cause I've learned I'm a pretty casual fan of SRPGs and have a difficult time not min/max to the point of boredom and never finish the games. I still haven't finished War of the Lions.
I've never played FFXIII-2 in any way, I have the free demo on my PS3 and I just can't bring myself to play it.
I've never gotten the Adamant Armor in FFIV, ever...
Even though I dislike FFX, I actually have a framed poster from the game that is one of Amano's designs hanging on my wall.
Despite my strong dislike of the VII Compilation series, I really enjoy Last Order, and I was disappointed that Crisis Core wasn't more like it.
