It's "normal" to be that addicted to a video game, but I would argue it isn't "right." It's one thing to have video games as a hobby, but if it's consuming his time to the point where he literally does NOTHING outside of it with you, then that's a problem.
Try talking to him about it, and explain how you feel. You can tell him that you're not asking him to stop entirely, nor do you need constant attention; you just want to feel like you and he can do things that don't involve sex or video games.
If you've tried this and he keeps doing it, I'd say try getting his attention some other way (maybe stop having sex with him? haha). If he still doesn't "get it," then maybe it's just not meant to be.
