The Secret World went in a very different direction with the same goal of mixing up the final experience. Not every quest is a matter of just clicking the right stuff in the right places. There are quests where the answer lies behind a puzzle, something to challenge the mind of the player rather than just your character's murdering arm.
In the case of the former, dynamic events keep areas feeling fresh time after time, but they've also garnered some criticism for their simplicity or awkwardness compared to normal quests. On the other hand, the latter is pretty stagnant the second time you're solving the same puzzle, but it offers you a mental tease you don't always get from MMOs. So which do you think is the more interesting breakout? Dynamic events or investigation quests?
