3 genders to be precise! And two past tenses depending on if you're telling a story or giving a factual account. Plus a lot of dative case use. And only 50% of the verbs follow standard conjugation. Also those sentance long compound words containing nouns verbs adjectives and adverbs, which you can make up on the spot and be grammatically correct. 

And don't forget how the gender conjugation changes depending on the case e.g. der is masculine die is feminine and das is neuter in nominative case, but dem is masculine or neuter and der is feminine in dative case.

Yeah German is a difficult language, but it does allow you to concisely express a complex idea with precision

I always thought latin was more difficult, but then again I am a native German speaker, so maybe that makes me a tad biased. :)
