This may seem foolish, but I wanted to call this to attention:
Video Games Aren't Allowed To Use The "Red Cross" Symbol For Health
The red cross and red crescent emblems are protected symbols under international humanitarian law and national laws. Any use that is not expressly authorized by the Geneva Conventions and their Additional Protocols constitutes a misuse of the emblem. Use of these emblems by unauthorized persons is strictly forbidden. Please contact the ICRC for more information.
While I don't think they will be knocking on doors anytime soon, forewarned is forearmed.
