After writing a... kinda long review, I'll resume it here with: play it. It is worth the time, way more than grinding gaccha games or all the stuff that often makes people uninterested in reading. Some lovely art pieces, more than worth a background to remember it, and a lot of interesting information too! Not like I was a book eater, but I do enjoy reading different sorts of insight while enjoying the media, and this has a lot of it. So, yes.
Play it.
