Yeah, it’s eighty bucks. Yeah, the 3DS is region-locked. Yeah, you won’t be able to understand any of what’s going on, in all likelihood.
But it’s New Love Plus.
You can (i.e. will) pre-order it from AmiAmi.jp here. You won’t regret buying this probably-good dating sim that you probably can’t play unless you own a Japanese 3DS and speak Japanese, in which case you probably are in Japan and could probably buy it there for a much, much lower price.
Otherwise, you can just stare at the box and imagine how good it probably is.
