8. A Gaming Chair
A chair absolutely counts as an accessory, as it's where you spend the majority of your time while playing. And if you buy the admittedly pricey X Rocker 51396 Pro Series Pedestal 2.1 Video Gaming Chair, you're getting so much more than a place to sit. This thing is comfortable and functional, as it features two speakers and a subwoofer imbedded inside of it, making immersion a guarantee.
