I liked GRAW1 in concept. It was a great game in my opinion and the difficulty I think is justified in a way because of its realism. However I did not like the fact of how the game played. No matter how good you are, no matter how well trained at coverage, troop coordination, etc. you are going to get shot and more than likely one of your team mates is going to bite the dust, worst it could be you buying the farm instead. Then what? You memorize where the guy is, reload the game, reset your tactics and give it a go. It just felt repetitious. Kill a guy, get killed, memorize where he is, reload save point, repeat . . . until mission is complete. I never really felt my use of tactics was really necessary because my initial approach tended to be wrong the first time. Its like watching a movie and knowing the ending. Only to watch the movie again and expect a new ending. That just doesn't sound like fun to me. . .
But I guess AI can't be all perfect otherwise why would we have multiplayer, right?
