Well, there was a 9 months gap between SC4 and Rush Hour, looks normal for me, whatever the quality of the game is.
Except Rush Hour was actually a very nifty expansion pack. The inner GIS nerd in me squeamed everytime I pressed the "show commute routes" tool. --- Number of people who claim that I'm an idiot because of my username, even though they were not born when I created my account nor ever played the first CoD: 14
Yeah.. and Rush Hour actually addressed most of the major complaints with the vanilla game like more transportation options and such. This new future cities expsion however is just a cash crab by EA and they're not even trying to fix the many problems with the base game. --- Live long and prosper.
