I think there's a user review site called mk2.net that gave XCX a 59, but people didn't take into account that the site is very harsh on games in general. For instance Bloodborne got a 66. I really have no idea what to think of a japanese user review site lol.
Dengeki Online apparently called it a masterpiece. Famitsu gave it a 34 (XenoWii got 36). Import impressions thread had some people loving it and some people hating it, but what else is new. It'll be interesting to see what western critics think of it, but either way I'll see for myself when it releases.
