Treyarch is not the same level as Infinity Ward
If Call of Duty: MW series are good movie, then Black Ops is just a normal TV show about War.
The Single Player mode uses so many CG to tell the story, but the game also be cut into so many pieces by that CG. I had counted, the shortest part of the playable game between two CG is less than 3 min. How can they do that? Also the AI of your partners are very strange -- sometime they are very smart, but sometime they are very stupid. The design of the game and the map is poor, they set something to limit your movement, for example, you will die if you don't move; you will be game over if you don't follow the CPUs.
Actually the Online Mode is better. The mode is different to MW2 and it is funny. However there are too little map and all of the map is not big enough. It is not MW2 there will be 18 people in the game at most! Some of the map is not enough for 18 people! I think Treyarch will add more maps, but it would also ask for our money to buy them.
I don't think it is as good as MW2.
