Maybe so. And that WOULD make a lot of sense as an actual explanation. I think the story was the developers said they could finish a new game in a certain amount of time. Which... is surprisingly fitting, considering the plot of the game itself.
You're telling me. And they even buffed up the graphics to the point where that N64 add-on thingy was required to play the game. That's a lot of improvement. How sweet of them.
