To be fair, translating a game like animal crossing was a lot harder back in the day, like in the gamecube version they actually did change a lot of holidays, just to make it culturally relevant over here. I'm pretty sure those holidays have become standardized, though. Like when japan got e+ on the gamecube they got the international holidays in addition to theirs...
but then there are holidays like "bean day" which involve "oni" and I wonder if nintendo was actually wasting time trying to invent a new holiday to replace it
The korean version has it's own unique holidays too, like "teachers day" where you get Red carnations, which I guess you cannot get otherwise?
Oh here's an important implication of the holidays being different in different territories: If you visit the town of someone who is in a different territory during one of their exclusive holidays, you can get furniture from their holiday in your game. Pretty neat, huh?
But anyway, the game is done now, they're just printing and shipping copies and waiting for the pre-decided release day.
Which is just 3 weeks away now.
