Dom II, feedback please

[Gin]

I have finished playing LOL and was pondering buying Dom II.
Or, perhaps, Civ 4. I just read this comment regarding Dom II in the LOL forum.
"Dom 2 is a completely different kind of strategy game. Dom 2 is a large scale, highly detailed strategy game, whereas Land of Legends is a small scale, highly refined strategy game.
The most important thing to know is that Dom 2 has awful single player - no campaign, and poor AI in skirmish. But if you like long multiplayer games, and have a few friends who also do, then it's a good buy."

Is the single player really that bad? If so, I guess I'd better get Civ 4.

Looking for feedback guys
