I dont see how people adventured in 3.5 FR. There were way too many npcs to make it worth it. Every last detail of the world was known. There was literally nothing for the dm or group to do at all. At least thats the way I felt about it. The 3.5 campaign guide spelled everything out there was no mystery in it. No unknown villian. There was really nothing interesting in old forgotten realms.
Why would any actor in LA ever spend time training to become a better actor? Why show up at an audition? I mean, who cares that Joe Johnson is some new actor, and could play Hamlet well when Brad Pitt is around, and way more experienced and well-known?
The whole argument about there being too many NPCs in the Forgotten Realms is just as silly. I've seen tonnes of people make it, and use it as a reason why they don't like the setting. But really....
Reading through the FRCS, there is a population of 69,702,416 people in Faerun, to say nothing of the populations of Kara-Tur, Maztica, or Al-Qadim. Out of all the materials for the setting, I bet there are fewer than 500 named NPCs. Having counted through the FRCS, I can say there are about 121 (I counted every one I could find in the geography chapter). And those are many of the major/famous ones.
Assuming there are 379 more in the other books, that leaves 500....which is still only 0.0007% of the population. These numbers are so unimaginably big that most people can't even really conceive of them. Consequently, 500 people are a tiny, tiny proportion of those numbers.
I really think that people overstate the prevalence of these NPCs. Faerun is a huge continent. There are tens of millions of people on it. What are the odds that your PCs are ever going to run into these NPCs? They're probably not that high.
I think back to my life, and I've probably met 2 famous people...Ronald Reagan and Bryan Mulroney. Both were by chance, and in both instances, they had better things to do than worry about what I was doing for my job. Why would matters be any different for the PCs?
These famous NPCs would be far too busy with the affairs they already have as responsibilities......taking care of their own business, handling the hundreds of requests for help that they get from locals (you want your cat out of the tree? It's kind of beneath me as I was killing great wyrm red dragons on the weekend, but you know my wife's brother's cousin's best friend, and well, I'm an all around nice guy, so I guess I will), giving autographs, and all that.
I just don't see that argument holding much weight. If the players are instructing the DM that they want to meet a certain NPC because the book says he lives in X town or building, or if the DM keeps having X NPC save the day, then the game has got more significant problems, and they're not the result of the campaign setting.
