Searching for Gamedev/UE4 related topics for by bachelors thesis

Good day,

i’m am looking for a topic to write my bachelors thesis about. I know that i want to do somthing Gamedev related, be it somthing inside the unreal engine, which i have the most experience with, or game development in general. I am also interested in the usage of AI in games.
My problem is defining a specific topic with a problem or question that i am going to solve with my thesis.
I was wondering if any of you had an idea for a more or less specific topic that may help me decide.
Since i am kind of late in looking for my topic, i don’t have too much time left.

I’m thankful for anyone commenting!
