I was wondering about how many game's mode will be in the game, i know about the main campaign and the normal sandbox mode, but there will be other kind of game's mode?

For Game's mode i'm refering to probably victory type, or maybe a mode with the Sorcerer king but without the doomsday counter, or something new.

I like very much the game at this stage but, while on one hand is pretty different from Legendary Heroes or Galactic Civilization and surely will be a new and fun adventure (a game with only one big bad enemy to defeat for victory sounds very cool), on the other will be probably monotonous to play the same game's mode over and over again switching only sovreigns, classes, races and things like this between games, then with different kind of game modes will be cool to play and explore all the feature every mode will offer trying different approaches, different strategies with different goals (offered from the game's mode we are playing).

Clearly this is my opinion 

Anyway we will have access to additional game modes other then the main campaign and the sandbox mode?
