I just watched the trailer and some G4 video on xbox.com about Midtown Madness 3. It looks like it's going to be very good. If you don't know about it, it's an online racer where you race the streets of Paris and Washington D.C. There's several cars to choose from, including the popular Hummer. It's supposed to ship sometime this spring, so if you haven't heard much about it, then go to xbox.com to find out more!
I really loved MM2 on PC so I've definately got my eye on this one! I don't have Live, nor do I intend on getting it anytime soon (down here broadband does not include unlimited downloads), but I still would like to purchase this for the other aspects and the fun gameplay.
