I think that gif of SC2 is very accurate. It is proving the game was designed with 16:9 in mind. It has nothing to do with how many pixels there are, or the image physically changing size. That gif is simply there to show field of vision, in which it clearly shows 16:9 has the advantage. If you can't see that 4:3, 16:10, and 16:9 are all clearly showing the same exact information in height, while the wider aspect ratios show more to the side, you haven't looked at the gif hard enough. 16:9 may end up with fewer pixels, but it is clearly showing more of the map at once because it doesn't sacrifice any vertical image space, it simply increases the width.
I know, I know, this is a pointless argument. But people keep getting this wrong and I feel like arguing, so there.
If you can't see what's wrong with those gifs then you haven't looked hard enough. They use the same vertical resolution, which is NOT WHAT ACTUALLY HAPPENS. In reality you LOSE resolution vertically. You keen banging on about showing more of the map, that's not the point, the point is NOT about how much of the scene you see, the point is it does so at the expense of fine-grain-detail resolution in the vertical direction.
The image will be less sharp vertically as it will be using fewer pixels to cover the same viewing area. Why do people find this so hard to grasp?
Whatever aspect ratio monitor you have you can always include more of the scene by reducing the ability to show small detail (i.e. having a larger viewing angle for the same number of pixels). That has nothing to do with the topic.
The problem is people are confusing 'resolution' with 'field of view', When I say 'less resolution vertically' that has nothing to do with what the field of view vertically is. It means _fewer pixels_. Which can either mean a smaller angle of view or it can mean loss of detail, but it has to be one or the other. Either way there is a LOSS.
