I was also thinking... what kind of game are you trying to put together?
If team-driven action and dungeon-mapping are not the core of your ideal experience, maybe a very different solution might work too?
FateLess is more focused on campaigns over one-shots, and individuals over teams.
Touched by Evil and Ikigai both focus on a single protagonist shared by the group of players.
Cerin is a lighweight (and lighthearted) game in between these extremes: team focused, one-shot, and less procedurally strict than L&A.
Then outside the realm of my games there is a vast variety of awesome titles that offer all kinds of gmLess solutions :)
What are you looking for exactly?
