I have contemplated starting these lately, but based on this thread I see that I probably shouldn't. I absolutely loathe anything that makes you travel long distances, because with the god-awful traveling in this game it becomes a massive time-sink. Doing nothing moving my mouse to turn every now and then for tens of minutes at a time is not my idea of fun. Doesn't matter if there's a good storyline tied to it, all that time spent wishing it was over is not worth a few minutes of cutscenes. It's the reason I'm not even going to do any more main story missions ever (apart from maybe getting DS Jaesa on my lowbie Mara).
Thanks OP, I'll stay away.
