EarthBound 64

EarthBound 64 would probably get most of the plot points that pertained to the later released Mother 3. In that game, chaos ensues after an invasion by the Pigmask Army, named after the uniforms, which resemble pigs, and its leader, Porky Minch, the "Pig King". They slowly construct a police state, while experimenting on the land's flora and fauna, and introducing new technology and infrastructure to the islands. The various chapters record the life of a boy named Lucas and his family and friends, banding together to rid the Nowhere Islands of the Pigmask Army.
