No, it is not perfect. Not even close. If everybody wrote just the name of the game they wanted to discuss, the list of posts in a community would just be game titles and nothing else. That would make it very difficult for people to easily distinguish what a post is about (and whether it warrants their attention or interest) without having to go into each and every one.

The reason why you don’t see this in action is precisely because it’s unhelpful to other people.
