DoW 1 is one of the best RTS's I've ever played. DoW 2 has a better storyline (by virtue of DoW 1 having very little storyline) but I don't find it nearly as fun or as exciting. If I want a real hack&slash, I'll play D2 or Divine Divinity or Torchlight. If I want a real strategy game, I'll play DoW 1 or Homeworld or Starcraft. I didn't even really find the tactics that compelling. You have, at most, 11 people on the map at once. And of those, at most 4 actually matter. The redshirts only exist to provide a meat shield for the squad leader. If you equip them with special weapons, only the squad leader actually gets one. Plus there's the map recycling thing, which is an issue with all three games.
It's a decent amount of fun, but it's nowhere near the many hundreds of hours I spent on Dark Crusade or Soulstorm.
