"quests are dynamic. even the rewards and the quest giver are randomized"
Hmm, so that mean that I can complete a hard a** side quest and get like 10 gold (septims in skyrim too?) as reward?
Or complete a easy side quest and get a 10000 gold?
"Quests are dynamic" refers to Radiant Story.
And Radiant Story does not equal randomness.
Radiant Story means that things in quests (locations, rewards (I think), enemies) will be set appropriate to certain factors. These factors could be places you've visited before, what you've done before for the quest-giver, what weapon you have, etc etc.
