When I was a kid, I thought Halo was about a robotic angel man named Halo. I watched no gameplay and knew nothing about the game, but judging by what I heard about it from other people, I thought it must have been the best game ever made.
All of those things turned out to be wrong when I actually played it though heh.
This isn't about 'game I thought was going to be good turned out to be shit', it's about things you thought the game had, that's boring. I wanna hear silly or funny things, like you thought a character was a different gender, or thought the story was completely different.
