Maybe you are already aware but just in case you aren't. The style "transformations" are not working, at all, on IE9 (WXP) and IE10 (WV). Not sure what "new" technology the website is using but I don't see anything that couldn't be achieved with technology available for these browsers.
When it comes to corporate image targeting a single browser or generation of browsers is not a good idea. People could think "If they can't even manage to create a good website for their own products, most likely a piece of software such as an FPS engine is completely out of their league. Next!" We all know that as end-users, all of us, can be very mean. Just a thought.
Other than that, congrats. The website looks great on Chrome (WXP and WV) and Safari.
