its definitly worth a try.
NOw, after that being said, i think i can say that the story is a whole lot better than the second. theres a lot more heart put into these characters and the backstories don't put you to sleep like Sons of Liberty did. Also, the villians weren't as bad as Sons of LIberty. Each villian was well thought out and the battles were really more fun than tedious. I guess i can say that the story saved the game from total embarassment and there was some old fasion metal gear action involved so that was totally awesome.
