Dedicated PC room considered harmful. Be part of your family even if you're ignoring them with your headphones on. Put in the work and manage your cables so the setup looks presentable. Get a nice looking chair and not a Gamer Chair. Get furniture.

You just made me realize something. Before I moved out I had my PC in my room and I'd spend an unhealthy amount of time there. After I moved to live with my girlfriend, I had no option for a room where I would be isolated with my PC. So it's in a shared space, I can game just as comfortably, but the fact that I'm not isolated makes me pause the game every so often and just talk to my girlfriend.

I don't game that much anyway these days, not addicted or anything, but even when I do immerse myself, there's always this impulse to take a break and socialize.
