I have to say... FF2 is pretty interesting. I was surprised to see some good innovation here for a game this old.
What I like:
~Playing the PSP Anniversary edition the graphics are improved even more so than FF1 was previously. Game looks like a top notch 16bit-er. And there's enough of an improvement from FF1psp ->FF2psp to make it feel like two different games
~Learning key phrases and then asking various NPcs about them. Sure not all the NPCs have responses for all the phrases but it adds something more than running up to people and mashing a button to get through text
~DUAL WIELDING. You can dual wield weapons with seemingly little penalty. My one dude has an axe and a broadsword going and he's fucking shit up. This also helps level crap up faster
~Music: love the battle theme and I'm glad to see new tracks all around. Esp after playing some of the DQ re-releases on the DS which both seem to have the exact same music...which shares a bit of DQ8 as well
