Gaming? No.
I hang out with mine while making coffee, or sitting at the computer watching videos (lately, fish and aquaponics DIY vids). The corn "roams" with me while I'm in the kitchen, and I've even stepped outside with him for the dogs, but he hangs on very well. Other times, he curls up inside a sleeve. The tiny kings stay in one hand. These sessions are daily, but brief. Maybe 15 min max. My main focus is on them while they are out.
Mostly, I make sure I know at all times where the main part of the body is for a firm grasp, and re-direction incase the snake starts to wander.
I live in an old house too. Way too many escape opportunities here. They would be hopelessly lost fast.
Just don't think snakes (esp. the reclusive BP) benefit from unsupervised roaming.
