GRR! Want this game so bad! But I'm not even sure I could play it what with not understanding Japanese and all.
The game's completely on rails (Like Fire Emblem), so at least you can't get stuck not knowing what to do.
Before I learned a lick of Japanese I was still able to feel my around Super Robot Wars EX- of course, I know Chinese and thus a lot of Kanji...
In the age of online guides though, it shouldn't take too
long for people to come out with at least a menu translation online, which is all you need to actually play.
