I wonder if the 4:3 aspect ratio is the intended 'true' resolution for the game engine. Since the game takes screenshots in that aspect ratio with the built in function, and the widescreen version looks a bit stretched out. But actually that's the part I can't tell. If the widescreen does in fact look stretched out, or if the narrower one looks too scrunched up. I don't know which is the real one. Did the people working on the mod assume widescreen is the default and make everything based on that? Is that even possible? So far I'm keeping converted jpegs of the tga's with both aspect ratios, haven't decided which I'm going with for posting more screenshots or whatever based on which one has more realistic looking human proportions for the models.
In the meantime, here's one of each for this mercenary phalanx phace off.
