Persona is just too confusing for me, having to manage both the calendar/social links and levelling.
Also, I was going to give Kingdom Hearts 3D another go today, but I'm still really hesitant on it due to how much I hated Drop-ing out of boss fights like it was nothing. I bought it within a week of release (for the right price, of course), and cleared the first world on both characters; I haven't played it since.
I just really hate gimmicks, sometimes.
