Super mario: We have already seen what this is like as a cartoon, as a anime it probably wouldn't be much different
Legend of Zelda: you would need link to talk otherwise it would probably get boring at times, and last time he did it wasn't great... at all... in-fact it was terrible.
Metroid: Samus as a anime would make sense, a space bounty hunter going to places killing aliens, give it a story line and a few characters you got yourself a badass show.
StarFox: After reading the manga, i would say keep star fox in games, it doesn't seem the type of series to have a great anime, it probably could but i can't see it :s
Kirby: Would be a good anime to have for kids on cartoon network, but besides that i wouldn't see many older people watching it.
Kid Icarus: Best Series to create a anime off, not only are the characters already in anime form, but we have seen some anime of them already, quirky funny character for comedy, badass epic fights and dramatic moments, all the characters getting along even when they hate each other would just be a great show to watch.
Fire Emblem: This could turn out to be a good anime for the older audience, Haven't played much fire emblem so i can't say much about it
Earthbound: i know NOTHING about this series, but a bunch of kids saving the world with Yo-yo's sounds good enough
Pikmin: um.... err... no? no... maybe? wait never! Doesn't make sense 
Kid Icarus Anime please!
