One thing to consider would be the wide open field for play. The Fatemaster will have plenty of leeway to create creatures and magic to his liking. If you enjoy creating mysterious things for discovery this is the place! Players in our group dive right in with backstory and motivations for their characters, which gives our FM lots to work off of. Our group of 5 had 2 campaigns running nearly all the time since we got the beta files. Now we are 8, looking for more fate decks (LGS's are OUT of them) and playing 2 sessions a week. We have a harlot, a penguin, an Arcanist, a Resurrectionist, 2 Tinkerers, a Chinese acupuncturist and assorted gunslingers and mercenaries as well as construct butler and a flying cat that is a tracker. All of the Fated look forward to what the future brings them with fear and anticipation. We have never had more actual roleplaying in our game than with TTB.
Edit: the penguin is actually C L O W N which the forum apparently objects to....
