BoardGameGeek is English-language, so the rule is that the primary title of a game is that of the first English-language edition
That may be the rule, but that doesn't mean it's the best one. I think it would be a better rule if the primary title would the title of the edition(s) that most people here actually own. Because that's what's on the shelves of the users of this site.
Yes, I'm aware that might be a hard rule to implement, since printruns and ownage of versions are hard to check.
It's just frustrating that everytime some publisher decides to rename the game BGG just sheepishly follows. This isn't the first time. I've even seen games renamed that haven't been published in English yet (probably based on intent or announcement I guess?).
Anyway, enough ranting for a lazy sunday.
