Interesting question @gvincentjosephm .
The thing about this is that you are the only one that can answer it.
these 2: object oriented programming and function programming are programming paradigms, which are basically about the way you code, mainly in order to be able to update & maintain your codebase.
Functional Programming at the moment does not look too friendly for beginners, it would rather be a really good tool for experienced programmers trying to improve on their monolithic app or micromonoliths.
However who is to say you can't jump a generation and start writing code that is less prone to mistakes of the past ?
Best thing going forward for a beginner in this space: whatever gets you going, there is value in making your own mistakes.
In the spirit of decentralized mediums as we are on a platform that's proof of that, reactive functional programming would be the best place to start when using decentralized systems or in your case a game that could benefit from micro-services.
