I see Dominions_3 as definitely worth it's value... even the AI has been significantly improved having 3 different settings:
Defensive, Standard, Aggressive.
(and maybe the option for the selection to be randomly chosen)

Maps have tripled in size, new random map generator, tons of new nations, items, and spells. Graphics have also been slightly improved. The game will also have greater modding capabilities.

I would recommend buying the game now and saving $7.oo.
