Dawn of War 2: Chaos Rising
Had my campaign carried over from the first game, and I COULDN'T CHANGE THE DIFFICULTY SETTING. Absolute nightmare to complete on Primarch (I think it's called), and the final level took me about a dozen tries. Good game, though I don't think I'll ever be able to enjoy it as much as the first without base-building and resource management. I sincerely hope they bring it back in number 3.
Onto Retribution now - not expecting as much of a story, but I think I'll prefer to play something other than Space Marines. I must have played the Dark Crusade campaign at least twice through per race, so if it has even half as much replay value as that I'll be getting my money's worth.
