expansions to what?  (this is the off-topic section which is shared between several game forums, to the best of my ability you are talking about Sins, but perhaps you know something about Demigod I do not yet know.   I would be very excited for a Demigod micro-expansion.)

If you are talking about Sins, the next expansion was already announced to be a diplomacy-focused expansion.  The AI is being vastly over-hauled and new techs focused on trading and such will be given. 

The only mystery is the 3rd expansion.  Butt he point is, your pitch (if for sins) has no point since it has already been announced.

if for demigod, it would be interesting to add a diplomacy and additional resources to the game.   Just "gold", "mana", "war effort' and "Favor" is a little dry.  Adding more resources might make it feel more like a strategy game.

Anyway, I recommend this post (and its 3 twins) be relocated by a mod to a less Off-topic section of the forum.  

The next Sins expansion is about diplomacy. Pirates will get some new features and the non-combat aspects of the game will be added to.

The one after that will likely add a campaign, but only if IC can come up with an original way to do it. I doubt new races will be added, but it hasn't been ruled out.

On the subjec of a DemiGod expansion, I heard that 2 new demigods were going to be added 2 months after release. Is this true?

Anyway, why did you post so many threads on expansions?
