At the very start of the intro video playback (before the "Welcome Brave Adventurer" text starts to brighten, but after the splash screen), click the LMB 2,3 or more times in rapid succession in order to skip the video. The game will CTD instead of going to the main menu. I'm guessing its overloading an input loop or something.
