Re;Birth 2's true end is actually what I'm aiming for right now, since the Conquest End was the first one I did. It's supposed to be the hardest to get last, after all. Since, well, lily ranks.
Re;Birth 2's harder because you have four members in your party out at the same time, as opposed to that of R;B1. They did a great job of raping you in the Coliseum, in my opinion. Still, dungeons are relatively easy now, since Symbol Attack On and Symbol Attack Gain. You literally get exp and money by hitting them while you're in the map. It kinda made it boring for me. But eh. I'll finish it.
Jumping Uni and Nepgear go!
