NOOOOOO......
Personally, I don't think they should ever make animes or mangas based on a video game. I haven't read/seen a single one that I enjoyed.
I suppose that if you're a serious fan of the series, it's interesting as a spin-off. But they're never good as stand-alone stories. They just don't adapt well. Now, as soon as I see in the plot summary "Based off the ____ game" I immediately decide to not read it.
Video games are great, manga is great, but I don't think game-to-manga adaptation works. They're different
types of stories, and you can't tell a game story with manga, and make it good. Sorry, you just can't.
