I can't stand it when the story is not well organized, when it is chaotic because there is no order, and usually,
non-linear sandboxes don't work because when you are free to do anything in any order but if you don't do them in a specific order then they are not logical, they don't make sense, because you miss something that you should have done before but since you didn't follow the logical order then the story is screwed up, the freedom granted by non-linear sandboxes is an illusion because there is always a certain logical order to follow, your only freedom is to mess up this logical order and screw up the story. π
I think both Black Cat's Demons of Harem and Kamos' Angels Humans and Gremory are worthless. π
