Meh, there is nothing unoriginal about VGMetal. Metal is the only instrumental art that has reached the level of variation in its approaches since Classical. There are so many type of Metal, I could not count. Heck, most metal fans like orchestral music.
So long as it's not stuff like Screamer or Death Metal, it could attract a lot of people. If it's Rap, techno, hip hop, R&B, country, whatever, it would turn off a lot more people. If you don't like metal, you haven't heard good metal, most likely. Not all metal is crazy.
Also, synthesized sound is bland, and annoying, I feel.
