We are playing Emerald Spire, using the fast/slow advancement suggested. If I understand correctly, I get 4 fame points for a level in fast mode, and 2 fame points for a level that I play in slow mode.
(Or less, if we don't complete what needs to be done.)
The "Land Rush" boons are available in either case, for a cost of 2 prestige points.
Pray forgive my poor searching skills if this has been answered already. I am not nearly as clever as this character, with her 16 INT and lots of Knowledge ranks.
