* ColbertBump: The series has gotten more than a few fans of indie [=RPGs=] after their creators have cited the games as a major source of inspiration, especially Toby "Radiation" Fox, creator of ''VideoGame/{{Undertale}}'' and Austin "Dingaling" Jorgenson, creator of ''VideoGame/{{Lisa}}''.
* {{Defictionalization}}: [[http://lvl1-chef.tumblr.com/tagged/earthbound This tumblr blog]] focuses on making real life versions of a lot of the ''MOTHER'' series food items, from stuff like skip sandwiches to pork chips to peanut cheese bars.
* DoingItForTheArt: Oh, yes. There is an absolutely ludicrous amount of detail in these games, especially the later two.
* NewbieBoom: The ''VideoGame/EarthBound'' fandom got a sudden surge of new members when the game ''[[KeepCirculatingTheTapes finally]]'' got rereleased on the Wii U. At one point it was ''the'' most downloaded VirtualConsole game on the Wii U, which resulted in many new comers to the series, with some being people who likely never heard of the game at that point. This has notably caused some friction between [[OldGuardVersusNewBlood those who were in the cult fandom before it gained a wider audience]], as not only are the newbies more willing to point out ''VideoGame/EarthBound''s flaws, they've even started to criticize ''VideoGame/{{Mother 3}}'''s flaws upon finding out about it, which considering the game was considered a SacredCow by those who were in the cult fandom...
* NoExportForYou: The series as a whole is quite possibly ''the'' most infamous example of this trope in all of video games. Only ''MOTHER 2'' was released in America back in the day, under the name ''[=EarthBound=]''. Europe got it even worse, as ''none of the three games'' were ever released there. [=EarthBound=] then proceeded to become a case of KeepCirculatingTheTapes for years until it ''finally'' got another rerelease during the ''UsefulNotes/WiiU'' era, which also finally brought the series to Europe. Then, some time later on June 14, 2015, the first game got an international release under the name ''Earthbound Beginnings'', nearly ''26 years'' after it came out in Japan. Only time will tell if ''Mother 3'' will finally be able to fully avert this trope some time in the future...
* WhatCouldHaveBeen: ''Mother 3: Fall of the Pig King'' was originally for the 64DD, then just the 64, then [[DevelopMentHell eventually]] on the GBA; losing international release, 3D graphics, 10 other playable characters, and who knows what else.
