[Wick]

In terms of content it's going from 30 themes to 60, from 1080 unit types to 1500+, the unit resolution increased IIRC from 32 to 64 pixels, ~475 to 600 spells, etc. So there's quite a bit of new content.

Of course, since Dominions has never lacked content, it's the new features that are most exciting. I'm very interested in the AI -- building castles is great but nothing else has been specified. Things like the autotax feature (does it look at blood hunters as well as unrest?) and any other tools to help with the MM are welcome. The random maps could be good, although going into Lairloch's Realm and learning how a 13 death caster with Cloud of Death can just erase an army probably won't be there.
