English is my first language and French is my second, and now I'm taking German, and I find it immensely easy. I'd like to learn Spanish, Japanese, and Russian as well, but one step at a time...

I actually think German and English sound a lot alike, and even look a lot alike, there are just different rules. For example, the 'die/der/das/die' instead of 'the'. That's obnoxious. I believe in Spanish there is 'el/la/los/las', and in French there is 'le/la/les' (all for articles, ramble ramble ramble). Japanese is so complicated-sounding. I don't like to drop my pronouns either. ARGH! And I want a future tense! RAWR!
English: I eat the hamburger in the dining room.
German: Ich esse den Hamburger im Esszimmer.
der becomes den in the akkusativ, im is in dem, dem is for das/der.
It seems complicated, but is easy to memorize.
(French: Je mange l'hamburger dans la salle à manger.
In comparison, I think German is easier for English-speakers because German accents, in general, are easier to understand. I've been taking French for four years and can barely understand the accents sometimes. Accents as in how someone speaks it, not é ç è ê à, etc. Learning the language can also depend on the teacher, and your own ability to learn languages. I have a very good German teacher, and I'm fairly good at learning languages, so my opinion might not be very helpful at all.
