It looks like it could be good, I have never played or even heard of the game and it seems like most game to anime series are not done that well, but there have been a couple of notable exceptions. Im not familiar with anything Dogakobo has done, but some of the names working on this have done some interesting series.
So, I saw the PC version and the XBox's one, and is it the same game and plot? Cuz they have different main cast and stuffs... Though I kinda like the PC version cast more somehow, maybe after learning from various players that Kakeru was even worse than the generic Harem male lead...<_<
well.. since it's from an adult vn, and they don't seem to have replaced anyone, then of course we don't know much about the staff.. you can't expect big star seiyuus to be voicing in h-scenes from the game, can you?
