Earthbound is fantastic, it's one of the most charming rpgs you can ever play, everything about it from the characters to the world and everything in between, the combat is quite simple so it would be fun even if you don't know anything about the genre.
My only problem with it is that the difficulty is kinda weird, the game throws a ton of random encounters at you and the bosses aren't that hard, which makes the bosses feel less important since dealing with the dozens of encounters before them is more of a problem than the bosses themselves
