GCSE Graphics Coursework Help - Board Game Project!!!!

I really want to get full marks on my Graphic Products coursework (if not an A/A*) however I feel like I'm constantly repeating myself, I cannot formulate ideas quickly or find any high grade examples to do with project which is a board game on the theme of travel. I am having regrets about my choice of task but I cannot change as I am too far along in the project (at initial ideas) how can I work to an A* and come up with ideas easily? What do I need to focus on getting spot on in order to get the top grade boundary?
