Transport Tycoon Forums

I really enjoy playing with the various GS that are on the game but i can not find a city builder script that works with the NAIS replacement. Does anyone know of a working city builder GS for multiple cities like the neighbors are important GS or a way to get a GS to work with NAIS? I have never made or modified a file to get things to work. If you know how to make one work please try to explain how without confusing me to death and to the mods, if this topic should be moved to a different place let me know and i will try to figure out how to move it. Thank you
