Wow, an actual new Mana game. Looks quite rough from the trailer but going to keep an eye on it. If the dress-spheres, sorry, class-changes, work mid-fight I could see myself enjoy that combat system.
I hated X because I found most of the characters sans Auron and Lulu to be incredibly obnoxious.
X-2 just made those problems worse by largely getting rid of the few characters I could tolerate, and somehow making Rikku even more annoying.
It says something about how good the combat was in those games that I managed to power my way thru X and a fair chunk of X-2 before it just got to be too much for me.
