I could imagine trying to bust Babe Ruth at Yankee Stadium while the crowd boos you just like in that old Ghostbusters 3 script. Not that I want to see that, its just something I could imagine. You know, thinking about that, it actually would be cool to have Yankee Stadium as a lvl (I'm not a fan of the Yankees, but that doesn't mean I don't consider the stadium to be an historical place). I'm trying to think of a cool ghost that would fit into such a lvl but nothing is coming to mind.
Going off-topic for a sec since I brought it up, but does anyone happen to have that script somewhere on their computer? I rather enjoyed it.
Wait, I know what we need to fight… A giant supernatural twinkie (35 feet long weighing 600 pounds to be exact).
