Seems normal and fine if its only 1x per week. My son is similar and likes to play computer games on the one day he is home. But we also use that day for random (usually fun) errands, maybe eating out, or doing a project, like he got a big lego set he wants to work on, or he is building something in the woods. We also prioritize earlier bed time on that night and encourage a full "take all the time you need" shower routine since ir can be rushed on other nights. He is 9 but will sometimes still ask to take a bubble bath. He occasionally invites a friend over or sees who is out in the neighborhood. Basically like the leisure stuff we dont have a chance to do other nights.
