If I was stuck with only Valve's output I'd run the fuck to almost any other console. I'd pick it over Virtual Boy and any other pre-GBA handheld but of major consoles? Nah, or I'd have to seriously think about it (there IS something to be said for the perpetual existence of TF2, CS:GO, and Dota 2.)PC is easily the best option, decades of Gabe's all on one system.
I am shocked to say this.. the Wii U.
I can play most Zelda games on it.
PC is the only sane answer.
Nintendo DSlite
DS and GBA games
Bright screen
Great dpad
I'm not sure I understand why we would just exclude one of the major benefits of PC gaming from consideration just because consoles don't share that unique advantage.
