I have read most of the posts...and that's a lot. There are reasons to agree and disagree with adding a jump feature. If someone jumping about in a video game annoys you to the point of anger, make an appointment with a shrink. Adding jump to this game would enhance quite a few different areas of game play. The biggest area would be the cut down on travel times in some cases where you "slide" down a small ledge but cannot get back up it and have to run for 10-15 minutes locating an access point.
