Just play the sandbox mode! Its been differnt for me everytime and is the meat and potatos of the game.
Just like Continuous mode in Dawn Of Discovery and Tropico3 is the meat and potatoes of those games.
The campagins are more tutorials..
Stories are my fav parts of games.. but SOME games dont need them (crysis, Tropico3, Dawn Of Discovery and Elemental).
RPGS are my fav genre and my rpgs NEED a good story, in my strategy games they dont.
Elemental is more focused on sandbox mode, give it a try.
