I personally found Aspects in Fate to be both inadequate and too intrusive. I think I compelled a PC once in a year-plus campaign. Obviously different people--and different groups--will have different experiences.This is one reason why I like having something akin to Fate Aspects. (Good job, Fabula Ultima!) It's easier for me to create complications or weave arcs when players have "guiding aspects" that work well for setting arcs up because it's simply easier for me to keep track of those things when they are written down. IME, it also helps players keep track of it because it's on their character sheet, and they can even be proactive about those character elements.
