Btw, played today multiplayer. All maps. Absolutely all maps in the game are uninspired as hell. Quantity over quality basically.
The reason why i found Black Ops enjoyable is because of the maps.
Modern Warfare 3 maps are boring as hell + they are not interactive at all. One thing that Treyarch did right with that shitty engine: making maps interactive even with the static physics engine they had. There are a lot of examples of interactivity in the maps.
Multiplayer is really boring. There is no depth at all. It's really bland and maps are a huge problem first of all.
