In recent titles Rosalina has become a very popular character in Mario Series because being the only one with a deep background story and not being a "Damsel-in-distress", becoming more popular that Peach, but despite her popularity, her apparences in Mario Spin offs is really low.
So far her only apparences in spin offs are "Mario Kart"
She haven´t appear in Mario Sport Mix or Mario Super Sluggers or any other spin off.
In Mario Party 9 has Whittles and a Galaxy theme board but no Rosalina
Why Rosalina has avoid almost all the spin offs?
Is Mario Kart enogh important to have Rosalina?
She is too importat for Miyamoto and SMB Staff?
What did you think?
