Suggested wording:

Fatal Error
OpenRA has encountered a fatal error and must close.
For more information, refer to the crash logs and FAQ.

[View Logs] [View FAQ] [Quit]

The logs button would behave as it currently does, and the FAQ button would open the FAQ web page in the users default browser (both `open` and `xdg-open` understand http urls - I hope something similar will exist for windows)
