So is this just for Rush Hour? I have the original non-Deluxe Sim City 4 and don't have the Rush Hour expansion. How does that work? As an aside, I emailed Aspyr earlier this week asking about a Universal patch for SC4 and was told they were working on it but had no release date yet. I didn't think they'd have it out so soon. EDIT: Looks like you must have Rush Hour installed for the patch to work. That's mildly annoying.
