I can think of two; The Corruption of Kiahoro is for early levels (1 to 3 but 1 would be quite tough) and it's follow up, Traveller which you can use the same character for (around level 6). They're both story driven, quest based adventures and last about twelve hours each. They require both Mask and Storm to be installed.

And there's also a character creator based on the Traveller mod if you want to level up a bit, buy some custom armor, or look at girls in their undies.
