having played galciv 2 (but kind of sucked at it)

were can i read whats new compared to galciv 3? (seen one or two of the youtube steam videos) beside the fancy grafics (and i approve ) but it was a long time ago i played galciv and want to purchase it when it releases (may right?)  

yes, galcivs homepage is a start but alot are "the same with new grafics" that i remember from galciv 2. (this from a person that just now found out that galciv 3 existed so take what i say with alot of "newbiesm")

this is a genuine question on were to start loocking for information on the game
