One kind of interesting twist on that is Fincher’s The Game. It remains unclear until the very end of the movie whether the main character is in a convoluted game where people are pretending to conspire against him, or an actual conspiracy using the game as cover.
I’ve always read that it’s because many light novels started online, and the way they were listed meant you needed the title to really grab folk’s attention.
(I actually really like this particular anime; the animation is often iffy but art and story really appeal to me!)
