A nice "adventuring" mod is the Contract Pack Anomaly Surveyor, which sends you around the whole solar system hunting for anomalies (and even adds some surprises). Everything that adds some "story" elements to the game is definitely appreciated! It even boosts interest in doing some missions which would be otherwise "boring". For example, after dozens of landings, maybe reaching the Mun is not fun anymore, until you suddenly find a mysterious "dot" on your scanners... As I said, the reward for solving the mysteries could be money, and/or science points, or just the fun! Giorgio
