In the campaign mode, the game is pretty good, though maybe a touch too easy even on SS - but it has good graphics & storyline even though the cut scenes can be a little tiresome, but I enjoyed it a lot
I read the forum before coming into MP (and let's be honest the PSN outage was a hindrance too), and was expecting a pretty buggy piece of work. I didn't get it though. It really is very good. I haven't seen any graining (yet) framerate is fine (haven't needed to change my head bobbing), no lag at all (yet), and no glitches. Haven't even seen any hackers/cheats.
Only one major criticism is that the network connection seems to drop out a lot (but that may be as much PSN's fault as anyone's), and a minor complaint is that the unlocks/assessments use is not ergonomic, it's not easy to understand what you need to do - but then I've seen worse.
Even the forums are pretty good, without the constant whining you get from people complaining about campers.
Now if I could just see my stats online it may be close to perfect
Just thought I'd share
