Eventually everyone tends to get too familiar and abit unhappy with the vanilla game. For those people there are varieties of game settings, special maps, game mods and nation mods, and even 3rd party programs. All of which are designed to make the game different than vanilla.

That doesnt just apply to MP play. It also applies to Solo play and to upgrading the AI. There are settings, maps, mods, modded nations, and 3rd party programs which take the AI far beyond what you might have played when you were going thru the demo or tutorial.
