A caveat: I can't seem to get the console to work for me. I have the bAllowConsole=1 line in my FALLOUT.ini file, but when I press ~, nothing happens. The prompt does not open off-screen (keys function normally as opposed to entering characters), which apparently sometimes happens. I even tried disconnecting my USB mouse and using the trackpad on my laptop, as someone mentioned that having a controlled plugged in blocked the console.
I'm playing the Steam version of Fallout 3 GOTY, patched to 1.7.
Help is appreciated, and thanks in advance!
