I don't actually see how it NEEDS Rush Hour to feel like Simcity 4. What on earth does Rush Hour have to do with Sim City in the first place?
Whee, we can now take "control" over a firetruck, and drive to the scene of the fire. Ofcourse, this driving is rather limited, more of a "click and it will go to where you clicked" deal than something even remotely resembling actually driving.
The only two things that are in Rush Hour that even have something in COMMON with a SimCity game, is that you can now have boulevards (which should have been in the game to begin with, because of that insane amount of traffic that seems to sprout out of even an orphanage for 6 year olds), and you can name streets, which is nothing more than a gimmick anyways.
Other than that? Ohhhh MISSIONS! Yeah, that's why people play a Sim City game, so we can have missions that will actually tell you "Failed". I mean, isn't that really why EVERYONE plays a Sim game? Because of the fact that you can FAIL at them?
Someone at EA snorted way too much laundry detergent, and came up with the dumbest expansion pack idea in a long time.
But, trust good old EA to milk it for all it's worth. Then again, that's just good business, since I'm sure there will be fanboyz who will buy both the expansion AND the limited edition... Sigh.
What SimCity 4 REALLY needs is another patch that takes care of that absurd abandonment problem caused by 10 people that can't find a job, and simply fuck up your whole town because of it.
