Unfortunately, it sounds like this Hakuoki title, unlike the one released earlier this year, isn't very good. (That's what a good percentage of the folks posting comments here are saying, at least.)
Still, I'm curious about it. Despite the fact that its gameplay sounds Dynasty Warriors-esque. (I'm not a big fan of hack-and-slash games. Shocking, I know.) Oh, and despite the fact that it doesn't seem to include any scenes in which Isami Kondou makes out with Shinpachi Nagakura.
I've yet to add it to my lengthy "to buy" list, though, because the folks at Aksys Games have done little more than announce their intent to bring it to North America and share its localized name (Hakuoki: Warriors of the Shinsengumi) so far.
More information on this PSP release is sure to appear on its official website sooner rather than later, though, so if you're like me and you're at all interested in it, you'd do well to pay it a visit every now and then.
