I think I'm done in the fifth chapter, as this stupid escort mission with a caravan just put me over the edge in frustration with the controls. I'm supposed to take out these guards as this caravan rolls through town, so I'm using my knives to take out guards at different heights, which makes for a combination of bad camera and slow response for the knives that just makes me want to cut my losses and transfer whatever I'll get for connecting this with AC2 and send this piece of crap back to Gamefly.
Honestly, I saw the title of this game having Assassin's Creed in it, then it being on a handheld and thought "This doesn't seem very promising." Guess I was right.
The first Assassin's Creed game got boring halfway through, and that is what is putting me off from Assassin's Creed 2. So, I guess I have a little paranoia about the series now.
AC2 fixes issues with the original like repetitive missions and much more depth to the side missions, collection stuff, and the economy. Bloodlines seems like an obvious rush job by a second tier team to come out alongside the big game and this shouldn't be taken as a sign of AC2's quality.
