If I'm honest, I'm not a huge fan of the Star Fox games. Though, I did enjoy Star Fox Adventures even though it's not traditional.
I'll also say that I'm not too big on Metroid games. (It could be due to the fact that I haven't given them a good enough chance. Apart from playing a bit of Prime & Super Metroid.)
I don't know what it is. I guess because for some reason the games feel so isolated in the sense that there's no characters apart from Samus. (That're good at least.) Weird excuse right?
I'd be interested in knowing if some people aren't fans of Mario or Zelda altogether. Pretty rare to come across.
