RPG dilemnas - Fate and Encouraging hesitant players

It occurred to me recently, following a character genning session that took an awful lot longer than I expected for a Fate Core game (so long in-fact that we had to reschedule the game for another evening), that a character creation system that seemed so streamlined and simple for myself may not be so for other; as a die-hard Fate fan I personally find the creation of Aspects and generating a character very simple and easy to do, because i've always got a fair few ideas for characters and the system allows me to create something that matches these ideas.

But what about people who perhaps don't have such a lot of character ideas buzzing around in their head? This doesn't make them any worse roleplayers by any means, however, whilst there has been some discussion about the fact that Fate adopts a certain approach towards a game and that it doesn't suit all games equally (after all no one system is going to be perfect for all styles of game "out of the box" as it were), perhaps the default method of character generation isn't necessarily suitable for all people.

I observed a few main "issues" during the character creation for a repeat of my Wild Blue one-off during character generation (I have put some suggestions for resolving this in blue underneath each point):

• Some players had difficult thinking up suitable powers or working out how to frame them within the rules system.
  Greater familiarity with the rules would help here and perhaps creating a list of example powers would have given them a good starting point.
• There was some trouble with thinking of reasonable ways to link the different characters together using the 'three phase method' listed in the Fate Core rulebook.
  Perhaps toning down the number of phases to just having a starting story/phase for each character and then allowing them to come up with their Aspects in a more freestyle manner; although doing this would then require a different method of linking the characters together.
• Stunt creation caused some notable pauses as the players struggled slightly with deciding on what they wanted their stunts to do.
  The example stunts listed in the Fate Core book helped in this regard as did referring back to the characters core concept.

I think that in retrospect I would probably have been better to create some (either fully or partially complete) pre-gen characters that the players could choose from and perhaps tweak to make more to their liking since, whilst I think having a full session for character generation is all well and good for a longer running campaign, it seems a little OTT for a one-off. Hopefully coming up with some pre-gens in future would also make it a little easier on those people who struggle with getting over that initial imagination 'hurdle' when it comes to creating a character idea.
