4. Final Fantasy II
I guess you could say I like FFII because I like Suikoden and other political narratives like that? Aside from the great music, I thought the narrative was pretty good. I think it can be improved in some areas (in terms of pacing), but I liked it. As long as you play the game without beating up your party members in an attempt to level up quickly, it becomes less of a chore to get through. I'd like to think it's one of the darker FF narratives, but gets overshadowed because of its battle/ability system.
A lot of people I know say it sucks, but on the other hand, a lot of people haven't played it because they heard it sucks. Or they didn't play it the way it was meant to be played (ie: not hitting your party members to level up). Sure, the system is flawed and easily broken, but I enjoyed it. But it isn't fun to beat up on your party members for most of the game because it gets boring, and sometimes doing this raises your stats disproportionally.
I mostly like it for its plot, though. It introduces a few musical themes (chocobo theme), traditions, and plot elements (death, war, betrayal, mission failure, etc) to the series. I think it's the FF that benefitted the most from later ports/remakes... and that it unfairly gets a lot of hate.
