You might be gaming too much if...
You find the hardest difficulties in games too easy. You own enough working consoles that you need multiple TVs. You own peripherals that most people won't know about. You bring more than just your laptop, its power cable and a mouse when you're gonna spend a long time someplace out of the house. You can pick up any class, character or weapon and immediately use it extremely well. You do not get your daily recommended dose of sunlight.
