Having just finished C2 the other day, I was pretty underwhelmed. I spent the last round pretty much hiding behind things to get past all of the enemies and I was able to complete the last four objectives in stealth mode - you'd hope when you triggered an objective the AI would be smart enough to react...
There are third party tools available that let you tweak the C2 graphics options to the point of insanity, but I found it pretty enough already.
The most annoying thing was the save game - why oh why won't they let you save at any point? It got to the stage where I was leaving the game paused whilst I went off and had dinner because I was in between checkpoints. So I wonder how much of the ten-hour playing time (yep, less then 10 hours to beat the game, pretty sad for a high-profile title) was actually playing vs paused.
