There are plenty of games (ours included) that dont have a story and are more typically arcade games or maybe sim games. I would say that of the dozen or so games I've rated so far only 1 or 2 tried to incorporate an actual story. This is going to cause a lot of inconsistency in rating story-less games - e.g. do they get a 1-star rating in this category for no story, or just a 3-star rating because the story isn't good or bad per se? I've been dropping 3-stars but who know how everyone else is doing it. When it comes to establishing an 'overall' rating there will be some very on-point on-theme games that dont get properly recognised because of this specific rating category.
