@Tristan Fishel they offer more freedom and character creation than DND since there's no classes. It's also easier as a GM because you don't have to worry about balancing anything. No matter what the players always roll the same thing they 2d6. Those are the two highlights I'll mention.

@James Willetts city in the mist is a noir detective style game by design and legend in the mist is more traditional fantasy. Same studio makes them both.
