I finished the GDI campaign in C&C3 tonight. I'd heard some complaints from friends that it was too short but I really don't feel that was the case. The GDI campaign alone felt pretty epic, and I still have a (presumably equal length) Nod campaign to play through. Actually I got as far as starting a few of the Nod campaigns, and as someone who generally likes the cheesy video sequences in the game just having a new set of people doing briefings changes the vibe of things a lot. Seeing actors from sci-fi fan favorites like Battlestar Galactica and Lost is kind of amusing too, even if none of them exactly rise above the source material.
Josh Holloway (Sawyer from Lost) in particular is basically playing his exact same character in C&C 3. I dunno if it's lazy writing or not, but it is kind of amusing in a very meta fashion...
Not directly game related but a friend recently turned me on to XKCD, a very very funny web comic, at least if you are on the same math-geek-gamer-linguist wavelength. There's a bunch there that I totally love, but this one particularly struck a chord with me... I had pretty much exactly the same reaction back at MIT. Personally, I take that equation as proof that we are living within a computer simulation...
