To generate ideas, I looked at other war games on the market to see how they engage the audience.
At the top of the home page, there is a clear navigation panel with allows the the user to easily navigate around the page. This is a very flat design, with not a lot of interaction with the audience to encourage them other than still graphics.
Throughout the design there is a clear grid structure which changes the lower down the page you go. Interestingly, They start from large to small sections as they move down the page, so there is a clear hierarchy of the main tabs of the page.
At the bottom of the page are small embedded videos which the user can scroll through and get excited about further content of the game. This section is more for enthusiasts so is positioned towards the bottom of the page.
