I am looking forward to this one but want to sample the single-player first. And I was hoping to get my hands on a single-player demo before buying this one. From the sound of it at least one of you has already played it single-player...
"DoW was a much better game, IMHO. Its storyline was much better... " Myself I haven't played through the "storyline" of a RTS since Warcraft II. I prefer to play skirmishes or different scenarios on different maps. But I would have to disagree that the story of WWII isn't "much better" since in most cases these games are using actual history for their storyline. But then it is all a matter of opinion.
If you're not tired of the WW II genre games and you like RTS this is a great game. I just hope they have a speed slider so that I can slow the game down a bit more.
