Hehehe I too have recently discovered how awesomely fun can KSP be.
Right now I'm trying to replace my communications network (Based entirely of the remotetech mod) since my first generation of satellites ended up in slighty different orbital altitudes and in the long term they ended up either too far away or too close.
I did have a very succesful mission recently in which I deployed three comunication satellites in a succesive manner around the Mun, land a Lander not far away from the Ecuatorial arch and from the lander I deployed a Rover with a robotic arm with a camera at the end of it. Everything fired from the same rocket. This game really gives you a warm feeling of accomplishment when you achieve the goals you set yourself, specially if they're complicated goals.
Personally, my main goal is a permanent base on Laythe, so far I have had probes there looking for nice spots and a single-kerbal mission. But I'm waiting on the new designed basebuilding parts, both stock and BobCat built... partially because I'm designing them
