Buy a ps5 controller to go with it so motion sensing is there (it’s awesome to use in shooter games like borderlands and tomb raider).
If you don’t already have a bunch of computer games and you know you’ll only be playing it on the TV (which would be silly, really) I’d probably say just get a ps5, though. That or someone’s used gaming computer for $500 and just hook that to the TV. If you wouldn’t use it outside your living room there are better options.
