Let's put it this way (I know I'm a noob, but still...) KSP doesn't tell you how much dV it takes to get anywhere. Just because it may tell you in the VAB or in mission shouldn't technically matter since you'll still have to go and look up how much dV it's going to take to go somewhere. For the people that have been playing forever you already know it takes x dV to go to y, but for new players they would have no clue without consulting the wiki or some other resource. With the potential changes coming to the engineer's report in the VAB I'm hoping there's a mention of "your vessel will reach orbit" and let you know the dV, but it should be limited to difficulty levels. As difficulty increases you get less info. Easy - All info, dV, will it reach space, will it orbit... Medium - dV info only.... Hard - no info. We need to remember this is a game at its core and in order to attract players it will need be be accessible to a wide range of people. Let the flame war begin! Edit: I also like the idea of this info being tied to building upgrades.
