I dunno why you guys are recommending the pc. Usually when people ask for a console, they really mean a console. A htpc is not a console, no matter how much big picture mode you throw at it. People ask for a console to plug and play, and exclusives, they're not looking for extra pixel here and extra frame there.
Semantics aside, I'd recommend the PS4 anyday over a budget htpc, it's the premier place for multiplats. It's cheap and getting showered with pc ports. Even the uber pc only game like Star Citizen is likely getting a port(ps4 dev kits spotted at studio). Considering the ease of use(plug&play no wressling with drivers and errors), and the unrivaled price/performance of PS4 at 399, it is the rational choice.
