Personaly, i've only played Hypno and it felt like one of the best corruption games i've ever played. And there is a Jap wiki with all routes that is pretty readable using google chrome "translate this page". Thinking about playing frontier now inb4 Ragnarok comes out.
Venus Blood games ( at least the most recent ones ) have instawin button that literally allows you to skip all the gameplay as long as you switch to easiest difficulty.
Is it me or most of them have some crazy hats? Or is it a new venus blood series direction they were talking about, like, give them the most ludicrous hats you can think of ? :)
