So the engineer state that it can run 'all games of the market'. Okay, cool, but at what kind of settings?
Like, it undermines the expectations of what one has when it comes to approaching the idea of having a PC to run games they want to see run flawlessly. I have been there before where I was not satisfied running games at Medium, hell, I wasn't satisfied when I ran some games at even High. My targeted goal of building a machine, is if it can run at least 90% of games that I throw at it, with optimum performance. Suffice to say, I think I've achieved that.
If someone gets a Steam Machine and find that it cannot run that particular game someone buys the Steam Machine for at their preference, you're going to see refunds flying around.
The Steam Machine development should've never went in with the concept of "just run games", they should've went in with the concept of "run games and run them well".
