Fun, but it wasn't worth the extra six month
If you have played Prince of Persia, then it is really easy to get the hang of Altair. the Free Running was amazing, and there is nothing more fun than running on rooftops and killing archers. However the archer missions were not so much fun. Making a "Director's Cut" to apologize to us pc gamers didn't go over so well. The new missions didn't add anything, and well the game so entirely the same. I really like the game regardless, come on if you're making a director's cut you need to change more than just four missions.
That being said, I really did like the game. The story is really compelling, with plot twists almost as good as Knights of the Old Republic. There really isn't great replay value, but I will be counting the days until the next installment comes. Oh, and I lost a bet with a friend of mine that there would be a Assassin's 2 trailer at the end of the PC game, and there wasn't, so I lost five bucks. But all and all an amazing game.
