Just out of curiosity, has anyone managed to get Gannon to open up to start the Enclave Remnants mission if you have sided with the Legion? I have attempted this and so far, no luck. According to the strategy guide, you have to complete Render Unto Caesar before he will open up on top of getting two "points" to make him open up. However, I am finding no way to do this successfully. The only way to actually complete Render Unto Caesar is to start the final invasion of Hoover Dam, which is obviously going to make it too late to set-up the meeting of the Enclave. Has anyone actually managed to do this yet?
