Yeah there's 4 (Technically 2) Metroids on the Wii. The Metroid Prime Trilogy ( Prime, Prime 2: Echoes, and Prime 3: Corruption) (Metroid Prime 3: Corruption can be buyed alone and is a good starting point) but the Trilogy can be really expensive. I bought mine for £40 at CEX. and then there is Metroid: Other M. There's also Metroid Prime: Hunters on the DS.

No, i have never heard of Sonic F. =)
