>Mother
One day, a man and his wife are abducted by aliens. The man eventually returns, but his wife is nowhere to be seen. He becomes increasingly reclusive and eventually passes away, leaving behind his daughter. The daughter marries a businessman who works long hours and as such is almost never home and has two children with him, one of them a boy named Ninten. Paranormal activities become increasingly common, until one day Ninten and his sister are attacked by a flying doll in her bedroom. As it turns out, aliens have invaded Earth and are the cause of this activity, and Ninten's grandfather had been planning and preparing for this ever since he returned from abduction. He'd left behind the means of driving back the invasion, which Ninten must travel the country to discover. At the end of the game you meet the mastermind behind the invasion, an alien named Gyiyg (Geeg), and defeat him using the secret weapon left behind by Ninten's grandfather.
>Earthbound
Twenty or so years after the alien invasion was driven back, a meteorite crashes into the hilltop outskirts of Onett, a city in a country named Eagleland. A young boy named Ness leaves the safety of his home to investigate and discovers that the meteorite is actually a spaceship and that its passenger, a psychic insect named Buzz Buzz, has come from the future. In that future, Gyiyg (Giygas in the English text) has conquered the world, and Buzz Buzz came back to the past to prevent this. Ness is then given the quest to journey across the world, visiting eight places of power to discover the means to stop Giygas's conquest.
>okay, but what do they play like?
Dragon Quest 2 and 4, but with a 1970-1990s aesthetic and a setting that resembles America (for Mother) and several other countries (for Earthbound). Earthbound and Mother 3 added a rolling HP Bar, which gives the player some leniency in surviving fatal attacks, and Mother 3 also added a minor rhythm mechanic to attacking, but beyond that they don't diverge from Dragon Quest's mechanics in any meaningful way.
>What's so great about them, then?
Nothing, really. They're mostly remembered for the games' humor, and are otherwise just comfy weird JRPGs.
