I’m catching up on watching Extra Credits and really liked the following two videos:
Quest Design II: This one continued the discussion of good quest design using both The Secret World and Lord of the Rings Online as positive examples. It really summed up well why investigation quests are so brilliant and engrossing in TSW.
Doing free to play wrong: Two things I strongly agree with here. 1. Make a good game first and worry about monetizing it later. 2. Present options that make us happy to spend our money on them, not forced to do so or trying to get around paying for them.
