First review, so I'm not sure how to get the hang of things here...
As you progress through the game, beat up defense-less animals, meet comrades who will aid you in your fight, some group of punks that dresses up funny, fight the Onett police force, a cult (that's supposedly based of the KKK) obsessed with the color blue, a strange race of "aliens" called Mr. Saturns, and much more.
The visuals were much different than other RPGs back in the 90s, they're colorful and fun. The music and sounds are pretty awesome as well. Nice tunes this game has in store for you, you should listen to them at some random video site.
EarthBound is absolutely a masterpiece, and YOU need to get your filthy hands on it. This game, without doubt, is one of the best RPGs in the world. Sadly, Nintendo of America hates EarthBound, because it didn't sell as good as they had expected. In the Japanese version of Super Smash Bros. Brawl, EarthBound was in the Masterpieces mode. Guess what? In the American version, they took it out. We know EarthBound came out in the US, but yet, it got removed. (Not sure about the PAL version though)
Try it, I don't (want to speak of) know how, but you need to try this game out.
It's GREEEAAATT!
