Lookit! A box! Isn’t that just the most exciting thing? The Internet is, of course, in a tizzy over Valve’s big reveal of a Steam Machine prototype, and – yep – it sure looks like one of them newfangled VCRs that can play those dang dern gametapes we never stop talking about. The bigger news, however, is that you need not worry about being required to own one – or even running SteamOS, for that matter. Nope, not even for Half-Life 3. Valve, happily, is philosophically opposed to the idea of platform exclusives.
