I'm going to be the most controversial one here. I'll ignore Call of Duty, sure same trout, slightly different, different day. Halo, same mechanics (well that's fine, they are after all the same universe it makes sense for mechanics to be the same) different story. These are all fine, you know what I'm aiming for...
MARIO
Why? Well because every new console Nintendo releases they go back and are like "Hey, you know what'll be cool? Let's re-release the exact same game we released every 5 years for the past 20 years with slightly updated graphics and a new gimmick included such as only being able to see Luigi on the Wii-U controller screen.
Please for the love of god Nintendo... let the fat old plumber get his princess and sit around getting noshed off with his feet on Toadstools head.
