Honestly, DoW2 was enjoyable to me, but Chaos rising was just.... boring.
It basically is a squad tactics game in the vein of myth, just without a lot of the "Casualties!" calls.
There's a lot of promise, but it seems to not have been capitalized on, much like the Space Marine game. One thing I wanted was a "Horde Mode" where each member picked a squad type, and tried to deal with ever more powerful waves of enemies. And we KIND of got it in Chaos Rising as "Last Stand" but instead of being a "Pick a squad" it's "Pick a hero" with only certain "builds" being viable to each hero (for example, a teleport/doombolt build for the Chaos Sorc is one of the most dangerous things to play, but does incredibly well in the hands of a micromanager).
Personally if they had put it in with the selection of a scout, tactical, devestator, and assault marines, and had players pick which one they used with a small loadout choice, then built a map around fighting off waves of enemies from one direction (like the defense missions in game) you'd probably see some more interesting play. Although the current incarnation of Last Stand can be pretty crazy when you've got like 8 dreadnaughts running around in one of the final rounds of the primary map.
