Well, I play SC4:Rush Hour for like few months, 5 or so. It's nice game, and so on. I dunno what to say more about it. Google for more info or so. Oh yes, and there are few sites for addons and mods. The most popular mods are NAM (Network addon mod) which includes some advanced pathfinders, new puzzle pices, and so, RHW (Rural highway mod) which was firstly part of NAM and now it's separet, it inculdes new type of highways which was firstly developed by Maxis but never finished, CAM (Colosus addon mod) it has some pathfinders too, and it makes residential, comercial and industry growth from 8 stages to 15 stages and so on. And there are planty of LOTs, BATs and other costume made stuff... Fell free to discuse and to put your expirience. My biggest town is 3k xD But I made "Money making tutorial" town to 12k (from 1k or 2k), and "Big town tutorial" town to 35k from 28k.
