Jordan Lund checks out Assassin's Creed 2 at PAX '09, and is concerned about gamers getting ripped off.
Excerpt: "My only complaint against the game is that it's not feeling unique. The assassinations look exactly like what we had just seen in the Splinter Cell: Conviction demo (hanging off a banister, grabbing a victim and throwing them over and down to their death.) There's a sequence in the game that could have been lifted from Prince of Persia: Sands of Time, where you leap and bound among roof beams and support poles to reach switches and open doors. They indicated that this style of gameplay would make up only five to six hours of total play time.
It's not that these borrowed items are necessarily bad, they are beautifully excecuted. I also love Splinter Cell and Prince of Persia, but the danger is having all Ubisoft Montreal games "feeling" the same. Nothing is going to turn a gamer off faster than charging him $60 for a game that's awesome, and another $60 for "more of the same". No matter how well done or gorgeous that "same" is."
