If it interferes with the rest of the game, certainly not... but realistically guys, I think that nothing will have to be scrapped to fit the advisors in. With a bit of improvement, they should be included, as they are a great part of the civ ambiance.

If live action talent is being considered for the game I strongly urge Firaxis to avoid the assumption that "passable" is good enough. Tongue-in-cheek will not cover up the damage done by mediocre talent in terms of over all game experience. Computer game makers have been notoriously easy on themselves in terms of live action production value, and Civ 2 was no exception. People who defend it usually say stuff the begins with, "I don't know, I kinda..." Firaxis has thus far been a pleasant exception to the no talent live action talent rule.

For example, I'd much rather have a few second footage of Allen Greenspan saying something cool about not ignoring the economy than dressing up some Denny's waiter in an Elvis suit and having him endlessly spout "It's about the money...Honney!"

If players get tired of them or just don't want to be bothered with them, have a setting where you can turn them off.

I agree, if disc space is at a premium - then have a 2-Disc Civ3 game.

As I mentioned in a thread over in Civ II Strategy, there are a number of clips that remain unseen in normal (competent) game-play. But they are very useful to the beginning player when something is going very badly, as well as being quite funny(IMHO), at least for the first 1000 times.
The problem is that the Council only spontaneously meets at certain predetermined intervals, and the novice player may not know how to select 'View High Council' when advice is really needed.

I like the suggestion that Sirotnikov made about having the advisors available on their relevent information screens. There could be a text box summarizing their advice, as well as a .avi clip for those so inclined. It would also be interesting if all of the advisors were available (clickable) on city build and research path screens: advice when a (novice) player might really need it. And if Firaxis really wished to make it functional, the player should be able to disagree with the advisor's initial suggestion, and get a second, or even third opinion from them, based on whatever is going on in their (or even other) areas.

Example: Science Advisor
City Build 1st advice - "Build a library" Fairly standard no brainer.

But now the player disagrees (or clicks on "Speak to me about other matters of importance...)

CB 2nd - "Let us encourage the study of science among the populace" Now advising the player to increase the science rate by creating scientists on the city screen (from the working population).

CB 3rd - "Build a diplomat/spy" Perhaps this city has been recently robbed of some tech, and needs protection, (and let us hope Firaxis fixes the undefeatable tech steal situation ,) or perhaps there is a nearby city of another civ that possesses superior tech...

Same thing for the Research Path. 2nd and 3rd advice may be for a certain Wonder that would benefit their area (maybe even one 2 or 3 techs away), or perhaps a tech that provides secondary benefit to their area.

Of course, this level of AI may be far beyond what Firaxis intends to include in Civ III, but I can dream, can't I?

But ofcourse the game itself should retire advices which aren't usefull, I mean, you wouldn't want your science advisor telling you to "build more libraries" when you have universities in all your cities?
