Whether CNQ ever sees conversion to CoD2 depends entirely on WHEN the tools are released and how much we have to work with. Honestly, most everyone at After-Hourz that does any custom work has lost interest in CoD2 already. You can check our site or drop some questions in the forums for better answers as time goes by.

As for your other gametype elements, you will need to worry about gamestate issues unless they raise the 16k. It will all depend on how much code you have to write and how many entity related things are going on and what gametypes you are running. 16k won't get you very far.
