It really boggles me that nobody develops on a widescreen, and boggles me further that noone in testing uses one. Even so, they should know that there is a growing group of PC gamers using widescreen monitors, they are getting cheap and are ideal for gaming, so why not?
Obviously the team put a lot of thought and polish on their game, but this, to me, is a huge oversight on their part. I thoroughly enjoyed the demo but felt like I had tunnel vision, and combine that with the jerky mouse movement (using 1 sensitivity in-game), I had to look around a lot to get a feel for the surroundings. I really hope they fix this in a patch, but Unreal 2004 had this problem, and it never got fixed though they promised they would, and this being an Unreal engine as well ... sigh.
