I just finished this game, too. All in all, a very good game and a much worthier successor to the original than the previous sequel.
After fight number 2 and 3, the final boss battle seemed almost anticlimactic, but there you have it. The third boss almost defeated me utterly, no matter what I did, and then I remembered
the turret on the very first level, down where the guards are patrolling outside.
Cheese,

but it allowed me to get on with the game.
I've started the Missing Link add-on, but to be honest I'm
dying to see if Skyrim will work on this laptop.
