Hello dear visitors! I, Isle Delfino Resort’s Manager, have news for you today.
I have done research for the rumors about a Super Mario Sunshine 2.
After research I can say that it’s probably not going to happen. The sequel Super Mario Sunshine was Super Mario Galaxy (1 and 2). So it is unlikely to happen, unfortunately.
Sorry to be the bearer of bad news. I do not know if they are going to remake it on the 3DS but is somebody has information on it please message me
