1UpJohn: As soon as I boot up the game, I can't move my mouse. The cursor stays at the center of the screen. I have to Alt-Tab to exit. Anyone know what the issue could be?
UPDATE: I found the solution. If you have a controller plugged into your PC, it defaults to that and you can't use your mouse. Unplugging your controller and booting up the game will allow you to use your mouse.
Had a similar issue, except with no obvious active controller plugged in. Solution was to go into the game folder, open up bsg_settings.ini and set GamepadOverride = 0.
