Yeah i got a load of powerglove on my iPhone, but if you really want the best video game influenced metal band it has to be "HORSE the band". been to see these guys like 3 times(twice in london, think i "blink and you'd miss it" appear in their tour dvd dancing my ass off, and saw them once in the states at
Hellfest that was fookin brutal, this was the last hellfest they ever did cos the place got torn apart)
Lot of zelda refences such as
Pols voice which is this
guy and
The Immense Defecation Of The Buntaluffigus which has the zelda dungeon theme mixed in with it.
Their best known song though is
Cutsman about one of the
megaman bosses. it even has a couple of audio clips from
The Wizard the biggest Nintendo advert masquerading as a film.
It's 8-bit metal-tastic!
And how could i forget the awesome
T.M.N.T you'd be surprised how it brings out the kid in you when you hear it live and start screaming "TURTLES!!!!!" at the top of your voice!
or for you purists out there you could go for
The Advantage who do very literal direct covers of old nes themes like
ducktails-moon stage(this is my ringtone

)
