While the IQ of the graphics didn't blow me away and they did look a bit dated, it did have the same art style of XII and that whole Final Fantasy Tactics setting, which is a good thing to me. Personally I am just not a fan of the quasi sci fi/modern setting that most of them have had since VI. IX's was way too over the top chibi to me. But I loved the aesthetic of XII and Tactics, and this seems to have it in spades.
With that said the battle system looked pretty cool, but I can't help but miss the final fantasy of old with parties and actual control over your party members. FFVIIr seemed to hit that better, and this one does appear to say "fuck it, it's too hard" and go for just a single protag. This is square so this thing is probably 4 years and 2 directors away from release still, so no need to really take too close of a look at it.
