Ok ... been lurking here as a guest for quite awhile .... time to take the plunge. ... Gotta agree with Aegrim. I did all the usual stuff with the Demo Version ... by hand. (you know, Launch, Orbit, Mun, Mun Landing, Safe Return, Safe Return to Space Port & Rendezvous) I only broke down and bought the updated version after I found MechJeb. Because all that stuff is .... Tedious .... (imagine that said with an exasperated sigh). MechJeb lets us do way cool stuff with all the other features because is saves hours and hours of gameplay time which would otherwise be spent doing stuff we already know how to do anyway. I\'d make the suggestion that some form of MechJeb be incorporated into the basic release.... (but, of course, I\'m too new here to make suggestions) .... perhaps MechJeb\'s features could be unlocked as the newbees mastered each new skill.
