I loved F-zero waay back in the old days, didnt like the N64 one, but enjoyed the gamecube one, it had some lovely features. They are different games and aim to do different things.

Regarding Pulse downloads for USA, well this is not official, just my personal opinion BUT given they havent been released yet, I doubt they ever will be, its a bit late now after all. Why ?
I've no idea, but to me it seems if they havent released them yet, then its unlikely they will for whatever reason

but like I said, this is NOT official in ANY way shape or form, it is just my personal opinion
