This is a list of the games i think were best for the wii and maybe some other systems.
Metroid prime3: Because it was the perfect end to the perfect metroid/first person series.
SSBB: It will be epic
note: heay i know there's not alot of greats for the new gens but its only the first term.
i also think Streetfighter iv will be great for whatever system it's on, and it's in 3-d.
