There does not seem to be a single Thread which contains a list of all the GAME LIMITS which one needs to bear in mind when creating a Mod or Scenario. There are threads which mention individual items, for example the GAME LIMIT for the number of units ( 4096) or Cities ( 576) or number of Resources (32). I think I saw somewhere that there is a limit to the number of Buildings (?82?). There is also a limit to the number of units requiring a specific resource ( the famous Hyperlinks Exceeded) and I cant remember if it is 32 ? I am interested to know if there is a limit to the number of diferent units the EDITOR and/or pediacons entries will accept ( its seems to be infinite !!). I am sure there is a lot of knowledge amonst Modders about this theme and I am hoping that this thread will stimulate the Community to pool and share this knowledge. I am also sure that I have missed a lot of other concepts that are subject to LIMTS .
