Mother: The writing is there but I'm not sure if it will translate as well
Pikmin: No. CGI
Star Fox: I wanna say yes... I also wanna say no... I don't know why I say this either way
Kid Icarus: Hands down the one I want and think is a great fit. It already has anime shorts and the game itself lends itself pretty well
Metroid: I think it would be best as a film series
Splatoon: This one seems like the obvious one. It already has a manga with two more on the way and the game lends itself pretty well
Golden Sun: Not quite sure.
