The sad thing is no one should have to create a group, good or evil intentions, to inform potential purchasers about the capabilities of a game. Publishers themselves have all of that information, what resolutions are supported, whether the framerate is limited, how aspect ratios are handled, even DRM implentation but are next to never forthcoming with the information. Though they will gladly take your money before any of that info is known. What we should be campaigning for is publishers to be more open with potential customers and just give us a bit of disclosure. It would go a long way to earning trust (well providing they aren't lying) and those who aren't as forthcoming with said details it might be worth holding off purchasing until the game is out.
I've long said that Systems Requirements are outdated and more often than not cause confusion than actually inform people. Something more in line with what system is required to achieve a stated resolution, framerate and level of settings would be more informative than just Minimum and Recommended. That's what we should be pushing for but you might be right in that something like the framerate police might make publisher more reluctant to give this information if they are met with hostility. We'll see.
