Assassin's creed got boring after the 2nd mission...
I only kept playing to see the end of the story...
meh.
But on a plus note, I did some REALLY sweet assassinations..
If you can try and set this up.
On any one of the early levels, grab the attention of your target and have his guards + him follow you. Run into a wall to run up it and jump in the air, now QUICKLY tap the assassination key, you should be able to perform a really ninja assassination move
It's hard to explain, but I'm sure you can picture it. It was my only cool part in the game.
