Well I was a huge fan of the original NOLF, infact it was my second favourite FPS after Half-Life.
But i was sorely dissapointed with NOLF2. IT does not means that it is not a good game. The graphics are great, the sound is awesome, the enemy AI is pot on. The Cutscenes and story is very good as well.
But all these things don't gell together in a way which would make it a classic, it just ends up being a very good game. But it fells short of being a very great game.
