That's actually (6) - a living room PC with Steam 10ft UI and a wireless game controller is a thing.
That's true to an extent, but it's also quite a bit more expensive than the $300 (CAD) I paid for an XBOX with 2 controllers, and I had the side benefit of being able to easily play with the kids (who find it easy to use).
Isnt such setting doable with PC?
Surely - but with kids, an XBOX also offered the ability to share the experience a little easier.
