I played Tales of Innocence on the DS using the Absolute Zero patch in the first half of 2011 - http://a0t.co/
. I thought it was pretty good, but the dungeons were really dragging and the mandatory grind got a little rough. I really liked how all the characters played, with the possible exception of Hermana (crappy magic selection, paper-thin defenses, and only redeeming value in combat was speedy combos).
What I want from Namco we won't ever get - English-language versions of the PSP/PS2 Tales of Destiny Director's Cut and the PSP Full Voice edition of Tales of Phantasia. I would buy Tales of Hearts R in a hot second, but I'm less certain of Innocence R.
