Good for you. I'm often tempted to do the same, I still play 2-3 hours a day of PC games most nights after work. It isn't healthy but then if I didn't I suspect I'd binge on netflix or even just regular TV instead. I think eventually I'll grow out of it and do more reading, cooking and other activities, but it'll take a decision on my part to make that happen.
I find I have about an hour before bed where I really shouldn't be trying to be productive (because if I keep coding or whatever, it'll actually prevent me from sleeping), where some nice video games or some passively-consumed video content can be slotted in guilt-free.
Now, I'm not saying that's the only time I relax, because that would be a lie. But it is a time that at least speaking for myself, I have to relax or I can't sleep.
The good thing about watching TV is that you can exercise at the same time. A few years ago, I realized that my time in front of the TV at night could easily be spent while also lifting weights and riding a stationary bike. My health benefitted greatly from that realization.
