Game makers: You can have wacky worlds and ideas without the need for ’80s references and breaking the fourth wall, so that it actually remains a world of its own that’s consistent and has rules. Even if those rules are silly.
When you use reference humour you date your creation, and you place it at a point in history. If you leave your world consistent with itself, it is only itself, separate from our world. That fourth wall helps hold up a universe worth remembering and returning to.
