Ever wanted to race in London's Underground? Cruise of San Francisco's roofs?
MM2 is a racing game set in two different maps: London and San Francisco. These maps are VERY well done and since they respect fairly well the real cities, they give a nice impression of what it is to drive on the Golden Gate or around Buckingham palace. Also, there's a great deal of cars There are various modes to play with. Theres a nice set of races taking place in different areas of the city (including the London metro). There is also a special feature for each city: a London cab school and a stunt driving school in SF. Plus, there's a cruising mode if you just feel like driving around in the traffic or in empty streets, with weather and time options.
The multiplayer can be a lot of fun. You can do races as well as games of Cops n' Robbers. Plus several user-made games include roof wars and bus CnR. Finally, if you know where to look, you can find hundreds of downloadable cars and dozens of mods and cities ; )
In overall, if you like racing games for pc, you're going to spend a lot of time with this jewel.
