Japanese is a dumb bullshit language for sure, but
>All the great classics got translated
The games you're thinking of are only classic BECAUSE they got translated. There are great games out there that likely would have become classics if only they had received a proper translation.

And for the record, Japanese games are more enjoyable in Japanese than translated. You can't think of it like a binary "translated vs. untranslated", because most older translated games are unplayable dogshit thanks to incompetent localizers like Working Designs or NISA, and many fan translations are equally incompetent. So there's more benefit to learning than you'd think, considering the sheer amount of Japanese vidya out there.
