Are Peach and Mario dating

Answer 1

Mario is currently seeing Peach only in his spare time. He is not looking for a serious commitment or dating relationship right now. She would say they are dating but he wouldn't label it that way.

Answer 2

No, In each of the Mario Series they are ambiguous about the answer, the same goes for Luigi and Daisy. Even though they do admit in the super smash brother's games in a description that "Daisy" is Luigi's Love interest.

Each of the "Baby" versions of the characters in each of the Yoshi's Story games or any of the interpretations of the famous characters are look back in the past. Yoshi's Story is just as that, a story of how Yoshi are so prized in the Mario world, expecially since they are a hidden race. the characters that are "shadowed" in the background are their parents which they never show or even say who they are, its to show that they do have parents and wasn't abandoned to their fate.

To once again sum it up, NO they are not dating even though the Mario brothers have love interests in their respective princesses (Mario - Peach, Luigi - Daisy).

What i would love to know myself though is who will be Roselina's Love interest? Will there be a new hero? Only Nintendo knows.
