Assassin's Creed 1 is not a great game. It's boring, slow, and repetitive. However, its successors, starting with Assassin's Creed 2 onwards, are excellent games. It's up to you whether you want to bother with Assassin's Creed 1. While this was originally a console game; the PC version is better and is the definitive version but is still a mediocre game due to the repetition. The PC version has more variety in the side missions that are required before each assassination, but I guarantee that the game is still going to seriously drag by the time you're halfway through. Still, I suggest getting it, if only because it sets up the story of Assassin's Creed 2, which is a great game that you owe to yourself to play. Trust me, AssCreed 2 really fixed many of the problems with the first game. Give it a shot if you have the money to blow, but don't expect the masterpiece that its successors were.
