Did to me. Things differed, sure, the Summon's were not the usual ones, battle/magic system was completely different (and random battles is something I associated strongly with FF games). But there was a 'feel' to it...*shrugs*
Okay so it wasn't that Final Fantasy-ee but it's a step up from FFXI and still a great game in it's own right. I am starting to miss a few of the things I associated with FF from early PSOne Final Fantasys. But games are changing.
