Andrei Dumitrescu, Softpedia Games Editor, reviews Command & Conquer 3: Kane's Wrath:
"There's a lot of content in Command & Conquer 3: Kane's Wrath. This is an expansion but there's enough in there to keep you occupied for months. The single player campaign is 10 hours long at the most and there ain't any replayability in it, but the Global Conquest is challenging, especially at a strategic level and you can spend an easy 30 hours on just one pass. And there are enough skirmish maps to keep one occupied for months.
The only thing that's not right is that the expansion doesn't provide any closure to the Command & Conquer 3 storyline. Whether the events at the end of the campaign are the Ascension that Kane talks off is pretty unclear. And there's also the little issue that the lovely GDI and the insidious Scrin didn't get any campaign attention. Of course, there's also the chance of another expansion to deal with that lack of love. Or Tiberium, the upcoming squad commanding shooter from Electronic Arts, could deal with the aftermath of Kane's Wrath.
In the meantime I can only say one thing: "One Vision, One Purpose! Peace through Power!"
