what engine are you using? there are some great engines out there that are open source(
http://www.sourceforge.org) and some that are retail. (
http://www.valvesoftware.com) I believe you can even use the Unreal engine, but i'm not sure. If you are talking about console development.. there are tons of forums to joing regarding homebrew development. Would you care to elaborate on your ideas? Lot's of people have ideas for games, but many never go anywhere.. how serious are you about this?
