here is the response i got back
Hello Joe,
Thanks for contacting EA Technical Support. We recognize and appreciate the effort that goes into game and product ideas and submissions.
We have thousands of employees world-wide who are constantly generating and developing game ideas, games and new game features some of which we build, but many we do not. Because of our creative scope, we do not look at unsolicited product ideas or game concepts from people outside of Electronic Arts.
We may review third-party products, but only after they have been built to a fully playable prototype (a working game). If you have such a prototype or if you have further questions, please contact productsubmissions@ea.com for more information about our submission process.
You may also post comments and suggestions at the Sim City 4 Forum (BBS). Thank you!
Should you require further assistance about this or any Electronic Arts games in the future please visit our website and review our extensive Self Help knowledgebase (http://support.ea.com).
