Can i work for riot as an artist and still have time for myself?

So iv been thinking about this for a long time, and its been really making me uneasy. I really want to work for riot games, but i dont want to be consumed by it so much that all my artwork is just for them and i cant do things i want. I want to work for them, but i also want to some day make my own comic too. I want to be able to play video games and spend time with friends and family. The reason i ask this is because iv been watching this guy on youtube called Kienan Lafferty, and he used to work for riot, but then quit because he felt like he had no time for himself, and now is working for them again but from home. I want to work in a studio, maybe even from home too, but i dont want to feel like i just have no time for my personal stuff. I want to feel like im a valued employee, but i really want to keep a part of me to more personal things. If anyone has experience with working for a big game company please enlighten me about this.
