As excited as I am for P5, I can't put it at number one for the sole reason that I know next to nothing about it. While I feel that for the most part I can trust ATLUS, I learned my lesson about jumping on the hype train early after Assassin's Creed 3. I'd need to see more before I can confidently say "I want this and am going to buy it no matter what."
That being said, it's still freaking Persona 5, so it lands cleanly in my #2. Persona Q, on the other hand, uses the Etrian Odyssey system, a series whose latest title received very good reviews. That way there's more basis for my expectations. P4A2 (while the other name is cooler, it's seriously a mouthful) is #3 because while I enjoyed Arena, I enjoy RPGs much more than fighting games and while I am really looking forward to Junpei and Yukari I'm not too sure how to feel about Sho right now. P4D sits at the bottom for me because I'm terrible at rhythm games. I do love the trailer though and how enthusiastic Lotus Juice is in it.
