Should Valve add an achievement scoring system like xbox/playstation?

Yes, I also think Nintendo really needs to embrace this feature for the NX.

I really expect them too. I don't know why they didn't have one on the wii u to be honest :P even the 3DS, that would've been cool. Didn't they have some patent earlier in the year for something like an achivement system though?
