Just completed the SP game on 'Normal'. Took 2 days, a little shy of 6 hours I reckon. This was on PS3.
To be honest, I enjoyed it. Lots of moments made me smile, and I particularly enjoyed the sniping missions with Price and the jail one. Playing through it felt a bit film-like, it wasn't exactly overloaded with cutscenes, but character interaction and stuff was very immersive. I didn't really understand the story... but manage to dumb it down enough and just enjoy myself!
One thing I will say though, I wasn't keen on the favela missions. Just spraying all over the place with no real objective was off-putting. Pop out, shoot, duck, out, shoot, move. Rinse and repeat. Still, I liked the whole thing, I must say I prefer shorter SP campaigns because I can stick to them and get them done, and the missions seem more interesting rather than 'Attack here, defend here, capture here' etc. Plus I have the MP component and 'Spec Ops', whatever that is, to get through.
Also, the very last mission was fantastic... such a cinematic ending as well as the credits. A+ for effort there IW
