As predicted a month or two back, EA has issued an expansion pack for SimCity 4, called Rush Hour. allowing players to “take charge of vehicles in their cities to drive or solve missions that earn reward buildings and vehicles. Players have the ultimate level of control over their city’s transportation network by completely taking charge of roads, rail, air, and even waterways.” It costs $20 (sheesh, that’s what the whole game would have cost a few years back.)
