>It is not that different from German in this matter.
Russian inflection changes the stress. In German it's fixed. Inflectional forms are much more varied in Russian. Colloquial German is much more analytical (past tense is almost always "ich habe" + participle). German has devolved to basically 3 cases at this point (with genitive dying out), compared to Russian's 6. But conceptually, they're very similar indeed.
If you just want to be understood, Russian is not very hard. I think it's true for any language. To master it, however...
