Or maybe I'm just bitter about Tales of Valor. At least with Retribution the campaign was worth playing through multiple times (as opposed to short and not worth it at all).
Personally, I'd like to see COH 2 cover the Russian front.
As for RTS worth it for singleplayer alone... Warcraft III and TFT, Starcraft, Starcraft II, Tiberian Sun & Firestorm, Red Alert 2, Zero Hour (not the original Generals), Red Alert 3, Company of Heroes, Chaos Rising, and Retribution (the last two because of their lower price tags).
Supreme Commander and World in Conflict felt the most "war" of them (mainly because they remembered the importance of displaying the War Map during briefings for immersion -- seriously, why the hell don't more RTS games do this), but due to the abusability of the expanding-map system I wouldn't call the campaign particularly good. The only really difficult mission was... I think it was the Cybran final mission, but it could've been the UEF's. I never finished WiC's campaign because it all felt too same-ish, but I'll probably get around to it someday.
I enjoyed Dark Crusade's campaign as a fun-mindless-4:00-in-the-morning-game kinda deal, but I always felt the campaign was just lazily designed, what with mostly just a bunch of easy skirmishes broken up by Citadel missions where the majority of the threat is surviving the opening rush (I suppose to make sure you've at least got a sizable Honor Guard or the Forward Base bonus). Then again, I never was a fan of DoW I gameplay to begin with. Continuously tapping R all the time got old. Very. FAST.
That reminds me... I should try and finish Soulstorm sometime...
