I guess I'm still to stuck in the Spanish three (Nominative, Dative and Accusative apparently) to know any better.

Nominative, genitive, accusative, and aperitif

Shit really? I thought it was three as well. D:

German has four

being curious about Finnish and looking into it and determining that that is waaaayyy more cases than I'm prepared to learn.

English pronouns still have three, but yeah, the vast majority of nouns have simplified to two. Latin has six, and I have encountered some consideration of locative as a seventh, but I think the consensus is six. But I remember

Uralic languages are much more complex though. Both Estonian and Finnish nouns and adjectives decline in 14 cases
