If you are really really new and innocent with the game, there is some potential help:
The science advisor will gleefully claim you're #1 (and thus are doing ok with science) or sadly give a different messge if you are not #1.
The economic advisor will do the same (we're rich, Rich, RICH) if you have way toooo much cash -- which may be weak advice for a different reason.
Elvis will put on a terrific show when a third of your cities are erupting in flames (not anarchy) -- Catch an early save with our D+2 game in the Stories & Tales thread.
The Foreign advisor does a decent job, probably the best of the bunch.
If you are challenged at Warlord, then the advisors may help you from making gross blunders (when two or more agree, then it might be a better idea...(hint)) -- but since you are checking out this website, you are better off just checking out these actors for pure entertainment only.
