Hello skimbo. My name is Luke and I come from Ireland. I grew up playing simcity4, and have been playing it for years, almost since it was new!! that aside, i recently got 'citiesxl 2011' and noticed that there are not many mods for it. i was wondering how you create different trains, changing colours ect. Is there software I can download to do this?? I am not a computer programmer or anything, so is there a way I can design my own mods for cities xl?? particularly buses and trains?? Please get back to me soon.
