Dated, derivative, multiplayer trash, laggy, glitchy and profoundly dull. The only thing I liked was the sandstorms that sweep occasionally across some maps. They look nice but it just means you run blindly around. Pity they didn't spend the time and money adding more to the main game, which is so good.
I don't think publishers care about what is good, just what will sell and sticking "tombs!" on the back of the box will only appeal to a small section of people, whereas MP is more likely to grab the guy who doesn't really read reviews and so forth.
