Your feelings are always valid! You need to tell him how you feel if you haven't already? And if you tell him and he still chooses games, then you've got a problem and you'll have to have a more serious talk with him about it.
Having said that, I've never been a "gamer", but I can see/understand the addiction to them very much. You can totally get "lost" and so involved in a game that you totally aren't "in the moment". Like, you're so into it, your mind is on it 100%, you're not thinking about anything else nor does it matter at that particular moment. Totally preoccupied. But... depending on the guy, don't assume that he doesn't care about you. So, yeah talk to him.

It's normal if he's a gamer. It's something u should have known beforehand. Try to talk to him and if talking doesn't work, it's time to move on
