The itch to replay FF4-6 is getting very severe.
I've beaten most versions of FF4. Funny enough my first one was the Chronicles hard type which was awesome. I actually like the PSP face lift though (really wish FF3 got that treatment, maybe even FF5 too). I feel like the original release on the SNES has a rough translation? Can't remember. The GBA version was weird, but that and the PSP one have the ATB bug so they're pretty easy. There's a lot to love about FF4's simplicity, so it's consistently been amazingly fun whenever I go back and replay it. Zero complaints. Even feels like it has potential to be my favorite.
FF5 I've only beaten once and it was the GBA version. Like we were talking recently, I'd love to get through the SNES translated version sometime. I predict FF5 being one of the best ones to go back and replay because the job system lends itself well to experimentation. Kind of like Seiken Densetsu 3 which I love to play over and over.
It has been quite awhile since I played FF6 by this point. Still the one I've probably beaten the most, but dang... it's been awhile. It's always too easy so I plan to limit magic to only Terra, Celes, and the old blue mage guy. I think it'll be pretty fun and more challenging this way.
Maybe I'll just play them all like I did one summer with FF2-5.
