Its a great game, one of the best I've played this year.  My only minor complaint is of the vehicle controls but that is like I said a very minor complaint.  I've played two characters so far, a soldier to level 15 and a hunter to level 9.  The soldier has been entirely single player and I did about 3 levels online with three random people.  
 
So far the coop has been hit and miss for me, my one good experience with random strangers I mentioned above was when all four of us were at almost the same level.  The other coop games I've joined have all had some high level player in there usually messing around with a friend and for me that hasn't worked.  I'm guessing coop will get better at higher levels particularly second play through but thats just my theory.  
 
Even if coop isn't your thing the game is a lot of fun single player and I'd recommend it to someone sitting on the fence.

Go with Diablo 2, just so many improvements over Diablo 1.  Don't get me wrong in its day Diablo 1 was amazing, I put many an hour into it, but Diablo 2 is the way to go.

Not worth the price, too expensive.

I have to go with video reviews, you get some footage to show off the game which could be good points or bad points depending on what the review whats to cover.  Its also easier to get the emotion of the review, an example would be Jeff's review of 50 Cent Blood in the Sand, you could tell Jeff just had plain fun playing it even with its faults.
