The Spirit of the Century game that I played in we had a really fantastic GM (Sam Chupp, who I didn't realize until much later who he was). He also implemented something he called "Fan Mail", which I believe he said was from Prime-Time Adventures (which I'm not familiar with).
Anyway, it allowed an alternative way for players to gain Fate Points, which is simply by doing something really fun, cool, or interesting that the rest of the party likes. There will be 1 or more Fate Points on the table that can be freely taken by any player at the table to give to ANOTHER player to reward them.
Anyway, Aspects, Fate Points, and Fan Mail all were really fun... but then again, it might have all just been because we had a great GM.
