Not necessarily hard, but the fact German has masculine/feminine/neuter articles for nouns seemed like a lot of extra work.

oh im just not gonna learn those for a bit 😂
Might be easier to try for it at the beginning. It affects the declension of the noun and I think some other stuff, from what I remember of my high school German class.
Don't forget about the nomintiv, accusativ, and dativ ridiculous rules. I was taught to never ask why they have them cause there's no good reason.
