GERMAN VS DUTCH

So, here's the deal. I'm stuck between German and Dutch (I know it's useless, whatever). I have pretty much the same resources for both, and am interested in both. Which should I learn first?
I would do Dutch but I've started back playing an online game which is available in German (among other languages), and I know that'd be a huge help using the language that much. Which do you think is easier to learn first?

Some background info:
I speak English natively. I'm at an intermediate level in Spanish, and the aforementioned game isn't in Spanish.

All English words come from Old German. And if I were you, I'd learn Dutch first (Flemish preferably) because your already learning German on your own. So yeah, start with Dutch.
