Gaming husband... what should I do?

So my husband and I have been married for 4 years, together for about 6. We met in high school, both joined the army, and are now stationed in Japan together. We also work together, like in the same building and room. So I understand having alone time once we’re home. I am currently 27 weeks pregnant with baby #1. We are also both 22, so we are still fairly young. With that being said, he is HUGE into gaming. I am too, but definitely not as much. For the most part our marriage is really good. I know he loves me, and I love him. The main issue in our marriage is literally video games. Insane right? If we’re home, he will literally play video games from the moment he walks into the house, until the moment he closes his eyes. And he will only stop if I ask him to do something (clean) or if I ask him to come do something with me. But most of the time he will wait until it’s like 9PM to get off and by then I’m too tired to do anything. And when I ask him to do something with me (like watch a movie) he does complain and acts like I never let him play. For example, today is Saturday. We woke up (around 9AM) and has literally not moved from his gaming set up and it’s 8PM. I asked him to get off and he said “I’m gonna play a couple more games, go get us food, and then we can watch movies” and I’m like YOUVE LITERALLY BEEN PLAYING ALL DAY!! It’s a constant battle everyday. Am I overreacting? I know we’re both still young and have some growing up to do, but we’re about to have a kid!! Has anyone else had this issue? Do you think it’s because he is so young, and will grow out of it? Ugh..maybe it’s my pregnant hormones?
