I have played EarthBound, but only LONG after I played Ness in Melee and Brawl. Melee was my first experience with Ness, and I absolutely loved playing as him back in the day. Reading his trophies in Melee made me REALLY want to play EarthBound. I remember dearly hoping for a Wii VC release of EarthBound, but that never happened. It was after the release of Brawl, but WELL before the Wii U's VC release (and well before the Wii U itself was even released) that I finally broke down and used an emulator to play it.
And by God, I regret absolutely nothing. EarthBound was just amazing to play. I later also used an emulator to play Mother 3 as well back then, with the fan translation patch. And I thought Mother 3 was even better. Mother 3 in particular ranks in my top 5 favorite video games of all-time.
Of course, once I got a Wii U (in November 2014), I did my part to legally support EarthBound and got the VC release off of the eShop. I'm hoping that rumor of a Mother 3 localization is true...
