I like Sunshine better. I just find the atmosphere of Deldino Isle amazing! Also, I liked the way gameplay strayed from the beaten path in Sunshine. FLUDD was fun and easy to use, and added a variety and uniquness to the game. The story is better too, IMO. Before I played Super Mario Galaxy, I said to myself, "This game sounds like it's going to be about Bowser taking over the galaxy and I'll have to stop him." I wasn't completely correct: He was taking over the universe. However, you can see how the plot was somewhat predictable. In Sunshine, I didn't know what I was getting! The island has been painted with goop? Cool! There's a guy impersonating me?! ******! Oh yeah, Sunshine introduced us to that character (I won't spoil it). The only inside joke that me and my friend share with Sunshine is Bowser's really weird voice... "Junior, there's somethin' I've gotta tell ya!"
