I think the Amount of Fame per-quest could be upgraded a little, i mean little, But as it stands with any sort of Effort you can build max fame in each zone within ~1 days of effort (A lot less if you're hard-core about it). Its a simple enough system with probably less tedium than other systems in place. Heck i had fun Fishing up the Items i needed in La'Theine, the other zones have easily repeatable quests as well. I know one zone has you collect Manigordo Fangs, In Grauberg(S) once you complete a certain quest, you can trade in the Wyvern-Wings-things(the (R) ones) for Cruor/fame, that ones pretty easy to do.

Its a tedious system, what isn't in an MMO, but it requires little effort, I think its decent as is :O
