Dissociation of selfish pleasure. Seeking advice on "fun"

If one's karma yoga is to not be selfish.

If the fruits of our actions are only for the gain of others.

Does this mean I can do nothing for myself that I enjoy? As in, no entertainment for fun?

Forgive my ignorance, as I'm merely just beginning my spiritual journey. The reason I ask is I've been quite devoted to my sadhana since Brahman found me, since I realized this is the path.

That being said, I do enjoy playing video games with some of my free time when I get it.

So the question is, does playing a video game for "fun" cause karma? Is it Rajas?

Help me navigate please.
