I wouldn't consider it "cheaper" than console gaming, but you can get FAR more performance from a ~$900 computer compared to a ~$500 console, plus it does everything else that a computer does that a console can't. Also PC games tend to be cheaper and are on sale often, plus you don't have to pay for an online subscription. So in some ways it's cheaper, but the entry cost is generally higher. I'm 24.
