Well I've been playing through origins and FF1 seems different in some of the less obvious places. I'm kind of pissed about the "evil" eye. It doesn't cast doom (aka rub) as much as it did in the nes version, but seems to like bolt2 more which makes leveling up there a little more difficult but oh well. It also seems like random battles occur more often, but that might just be me. But damn is that new music awesome. I love the updated town theme with the classical guitar and flute.
I guess we can use this topic to post anything that you come across that seems different (but not just names because those are pretty obvious).
