Naming is an interesting topic. There are several perspectives in this case:



If the game would've been officially released outside of Japan in the 90s – which of course was a non-starter since it's a 1998 SNES game – I'm sure PR would have cooked up something completely different than the [Console] Wars scheme. Also, we're talking about the 'tude era here so Xs and Zs would certainly have been squiggled on the white board...



Or they could have gone the Sim City / Tetris Attack route and incorporated some well known trademark in the localized title. Wario Wars is the dream scenario here, but we're still a few years off from Wario's prime, so Mario & Luigi Wars maybe (Red Star and Green Earth have their colors, so we're golden!). Pikachu could helm Yellow Comet and as for Blue Moon... Meta Knight?



Bottom line is that Super Nintendo Wars would have been an unlikely title at the time.



Anyway, in Advance Wars fan circles this game is firmly established as Super Famicom Wars. And since I don't aim for a full on "hypothetical of the era localization" Super Famicom Wars it is.
