Is there any overview of all dom 2 -> 3 changes?

[PhilD]

There are some more subtle changes, but here's a non-exhaustive list:

* more nations

* themes are gone, now nation variants are represented by "ages" for all nations - but unless one does some complex map scripting, games don't mix across ages, so Ulm Black Forest (now Ulm, Late Era) won't meet with, say, Avalon Man (now Man, Middle Era).

* you get to choose whether you get your Pretender on turn 1, or about turn 12, or about turn 36. The later, the more design points you get

* random map generator included in the game

* and, as has been mentioned, a huge (300 pages) manual, with detailed explanations of most game mechanisms and full lists of spells and items. No list of national units, though, which is unfortunate.
