10yo obsessed with video games

Update: I really appreciate all the suggestions and even call of concerns to our parenting style. I wanted to give an update that we've taken the suggestion to give him a bucket of hours a week of screen time that he can choose to manage how he wants. We bought a large digital stop timer that can turn off and turn on but still pick back up where the timer left off and it's been working great. Our son is pretty optimistic about this too and even said he likes the idea of being in charge of his time: we set rules if we find his chores aren't done right, we subtract time from the timer. My husband initially wanted to give him 9 hours a week but I proposed instead still 7 and allow our kid to roll over extra time into the next week if he hasn't eaten it all up by Saturday night(timer resets Sunday). It's Thursday and he's down to 2.5 hours lol so I don't think much will roll over very often unless he gets better at managing his own screen time. Anyway, thanks again all for the suggestions

Hi all, I need some serious advise if this is too much but we are running out of ideas. we have a 10 year old who is only concerned about video games. He will half complete a chore and rush through anything to get home and play video games. We split his time between his mom's house and ours. When she calls he'll rush through a conversation with her and hang up to go back to his games. Shoot- we were at a convention that he particularly liked the subject of and half way through he became irritable and "tired" because he wanted to go home and play video games. He does have diagnosed ADHD, and we work on it with daily routines at the beginning and end of each day, monitor homework closely, study for tests together in a fun way and give him fidget toys during movies and repetitive tasks. He use to have screen time limited to only an hour for video games a day but we realized quickly that he does not learn the skills to manage his own screen time and that could really hurt him as a teenager or young adult. My husband (who is sick with COVID) tried something new today after our son thought it'd be appropriate to wake him up to ask him if he could play games instead of playing outside, play on the trampoline, play with his toys, or literally any other activity around the house. Husband told him "okay, if video games are more important than other people's feelings and more important than your responsibilities, you get to play video games the rest of the day but only Tony hawk pro skater and you can only do this one map. As someone with adhd, being forced to do the same thing would be torture and so I feel like it's a bit much.. but at the same time, he has to learn investing his time and energy into video games has no benefit long term, it's merely a casual fun past time activity. My husband and I love video games and definitely play together as a family but we know when it's bed time, time for work, time to clean. Again- he's 10 so we don't drill him too hard but he has a morning routine, after school routine and bed time routine but he'll half completely tasks or hide things and lie just to play games.. our kid is on hour 2 of THPS and is bawling and SO upset 😭 I hate it. I told my husband to make sure he understands what "too much" is before our kid gets to that too. Any advice on if this is bad or fine? Any other creative ways to handle video game obsession in tweens?

Edit: we do not let him play games all day 😅 I can see how that got lost in my frustrated translation. It's not a firm regulation but our general rule is: is your responsibilities done COREECTLY(we made a detailed check list to help him make sure he didn't forget a step), does anyone in the house need help with anything? Is the house clean? 😂 I promise we do not blindly give him screen time all day anytime. He's just so obsessed and I'm anxious if we limit it to one hour he won't learn how to manage his time.
