User blog:RetroNash/Why does Rosalina keep getting included in EVERYTHING?

Don't get me wrong, Rosalina is a great character. She is actually my favourite female character. But I just don't get why she is included in almost every of the latest Mario games since Mario Kart 7. Mario games like Mario Kart and Mario Party are fine but she is playable in even Super Mario 3D World and Super Smash Bros. Why? Are we seeing the year (Or two) of Rosalina?
