I thought that perhaps a few of you will find this Dawn of War II mod very interesting, assuming you don't know about it already. In the author's own words:
Codex Edition is an attempt to recreate the feel and intensity of the Warhammer 40k universe in a way that many players felt was lacking in the origninal DoW 2. Specifically, it is a blend of TT elements and background/fluff from 40k material to provide a more exciting and immersive tactical war game.
Here's the topic for it, and it contains video demos for each faction showcasing what changes they have made to the game. I watched the Eldar demo and was quite impressed, though not sure how balanced these changes are, they at least look like good fun.
