I was just stating the norms of Japanese devs being bad at English. Not blaming it as the marketing direction is totally on the devs. One could argue the controversial marking worked and the game got more popular because of it.

For me, as far as marketing goes, trailers > reviews > steam description.

The most important part is try it. I tried Paradox games a couple of time, a couple tries later and I could see why people are into it.
