Yeah, this can pretty much be done in a day. And sadly, the rewards aren't exactly setting the world on fire.
A few unique pets...
A recolored Sand Person outfit...
A junker speeder from one of the quests, in case a sparking, on-fire vehicle really tickled your fancy...
And weapons for very specific characters...
Some of the quests were kinda cool, and it makes me think they were showing off new gimmicks for quests or such than they were giving us presents.
