is there any limit to how big of a lot you can make for sc4? or is it unlimited as long as it fits in your city's land... if there is a limit, what is the largest x by x lot allowable?
The SC4D Wiki may be able to answer your questions, especially here

:)
The size limit is 64 x 64 tiles in length so exactly the same size as a small city. However there is also a limit to objects that can be put (base and overlay textures, flora, props) which is about 1200. If you exceed this limit, the lot will automatically delete textures and props once plopped in the city until its within the boundaries . Hope this helps. ;)
More information about the object limit of 1280 can be found here (http://sc4devotion.com/forums/index.php?topic=6862.0). ;)
