I just don't understand this argument about widescreen being a cheat/unfair advantage. Both CS Source (and in effect all source games) plus CS 1.6 (in effect all GoldSrc games) have full widescreen support, 16:9 and 16:10, with zero issues. Absolutely no-one complained about the widescreen support, and welcomed it in fact. Being two games that are fairly competitive, if widescreen was such an unfair advantage there's be far more complaining about how widescreen gamers have an extra advantage over all others and so on. CS players are known to be fairly vocal in their complaints. But there's was/is still next to nothing to hear about it.
But with the BF games, oh no! Widescreen is too much of an advantage, and not only that, people start defending EA/DICE for some reason and agree with this being the case. Why are people defending BF2/BF2142 and not having issue with the many other games with full widescreen support in multiplayer? Damn fanboys.

Just because Valve doesn't classify it as being an unfair-advantage doesn't mean it isn't. Clearly, all bias aside, seeing more on screen than people with non-widescreen monitors is an advantage, no matter how you look at it. All I am saying is that EA chose to include that as something they feel the game should be without. Hence, not including the resolution in the selection, and kicking people with Punkbuster. (I am not sure if Punkbuster is run by EA or not, but it doesn't really matter.)
You can complain about their standards all you want, but EA will probably not listen, or care.
