The problem, as with many such mods, is aligning the stars so that you can get it all running. At last check, you need a PS4 with a relatively ancient version of Sony's operating system (1.76) to jailbreak and install Linux. Also, there's no simple package that includes everything you need; this will require some elbow grease. There's talk of a possible jailbreak for much newer software (3.50), though, and it won't be surprising if it's eventually trivial to run Steam games on the same system you use for Uncharted.
