it's a sad state of affairs today, and for this industry, that so many people who call themselves "gamers" worry about such trivial issues as number of pixels on a screen and framerate.
Of the 2 framerate is obviously the most *important* aspect because it affects how the game plays... but otherwise....
How a game looks is part of enjoying gaming.
Higher resolution looks better.. high framerate looks and plays better, and it takes more powerful hardware to achieve those things.
In the end, gameplay is king.. and the difference may not bother some people.. hell, as long as it's only resolution, for some people's TV sets it really wouldn't even matter.
But if I have a choice, and the gameplay is the same across the 2 platforms I own.. better graphics is going to play into that choice. It's just that simple.. and for people choosing platforms, considering gameplay is relatively the same.. it might make the platform choice for them.
To someone else, better or more fully supported voice and motion control might be a bigger deal, etc.
It is sad how huge of a deal people make and how dramatic they are.. but your post is almost equally dramatic, as it attempts to claim that resolution and framerate are "trivial".. they really aren't. Go play a 1x1 resolution game at 1 frame rate... you can't..
While obviously the "return on increase" is much lower once you reach a certain point.. it's still an increase. 1080p is more clear than 720p.. 60FPS plays better than 30FPS, etc.
