Well, I really enjoyed FF13. I love the characters, the music, the gameplay. But I love the FF games that are popular to hate, FF8, FF12, and now FF13. I also hate HATE HATE FFX and I found FF7 underwhelming because I played FF6 first and felt the materia system was a step backwards from FF6 version. And I felt FF7's story went down hill when you left Midgar. Bah, flower girl I did not notice you left. Tifa all the way!
I for one am excited that FF15 is trying to break way from the ATB system that FF has had forever. Though I suspect people are jumping the gun by saying this looks more like Devil May Cry. I do think we will still be using a menu based system but our characters movement might be far more open. We know too little about the combat system to say much of anything.
As for the FF15 being a Fantasy based on Reality, I don't think this is meant to imply that the artwork will be super realistic but that the storyline will be tied more closely to characters with realistic motivations. Lets face it, villains like Kekfa and Sephiroth were never presented as realistic.
Also, about the main character looking emo, I'd say don't jump the gun just yet. It does seems like we are set to make a return to the days of FF7 and FF8 with emo lead characters but it could just be the Noctis has a reserved and maybe somewhat shy personality. When hes friends with the seemingly rebel blond guy (stereotypical japanese rebellious youth look lol), Noctiis might prove to have a more outgoing nature then he appears to have.
