Come back after you play through most of a campaign. I sure you'll determine that the SP Campaign is vastly improved and may very well be the equal of the Battle game.

CA needs to devise a new demo, that reflects the Campaign Game and Strategy Map. Otherwise people will continue to not get the "full" impression of the game.

It's also, IMHO, why so many TWers are so focused upon the battles and MP, while giving the SP Campaign short shrift. The demo attracts the, "fight, fight, fight", RTS types and fewer of the Civ2/3 and RRT2 types.

Also, if CA were to apply the time and resources to developing a MP Campaign (even a limited version), Total War would EXPLODE!! and probably revive the PC as a game platform. It would be the best game ever produced.
