Oh the release most assuredly should not be well after release of the game. My thinking is basically if it comes down to having to delay the game, or release the GM mode a bit after, I'd rather have the game first. Heck, I'd even be fine with a solid, well polish lower featured set of the GM mode with updates to come to expand on it. I'm super excited for GM Mode though, and it's probably one of my favourite pieces.
