Yes there are alot of limitations. First off you NEED Darklights and DarkBASIC Professional. They only give you the engine source code, not the mapeditors. The source is pretty raw, meaning that if you modify it to much without being aware of everything that you ARE modifying, may cause it to crash, or just not compile, so be aware of your surroundings. Also, we can only have the version 1.07 source coding, meaning that people that use your mod must be using version 1.07 or 1.08. (some mods work on early betas of version 9) .
Also, there are bugs that sometimes cannot be fixed by you, take the dynamic light problem for example, that cannot be fixed from the source, because It's a difference in a version of one of the DBP DLL's that Lee has versus the one we get. (thanks Airslide).
As for the AI, I can't answer much of that area, although it can be modified (I think) to your limitations.
Hope this helped,
