In wake of the recent memorial thread for the late Hirotaka Suzuoki, I have remembered that news of this game reached my ears not too long ago, as well.

It appears to be a hack-and-slash focused around the Kyoto Arc, meaning you'll go around as Kenshin, Sanosuke, Saito, and (sometimes) Aoshi in character specific battles that span the full 11 volume saga.

While I must admit that I am happy to see a Kenshin game made at this time, I'm also sort of disappointed at how it looks, at the moment... Outdated graphics/animation and repetitive gameplay do not an enjoyable game make.
