Other than the Type S scout, I tend to favor small merchants in games as ships for players. In areas of known piracy, there are usually established trade routes that have escorted convoys of merchants moving along them. The problem for players is convoying is an economic negative as you have to wait, sometimes, weeks to go on the convoy. Do you wait or risk going it solo?
Anyway, far traders like the Empress Marava or the Beowulf are what show up in games. I tend to try to avoid having players in serious combat since, unlike many other RPG, they tend to end up dead or wounded--often badly--as a result. Yea, combat is something to avoid, not seek out...
