Gaming in general isn't a cheap hobby. You can get a 320$ steam deck, dock it and plug it into an old monitor add a cheap KB and mouse and you are PC gaming. Or you can spend 3,200$ on a top of the line rig. Its whatever you want to make of it. I wouldnt say its more expensive than console gaming, but you can make it one and you will get a better experience for it. Either way personally I would consider PC the best option by a fairly large margin.
