I don't understand what's so controversal about Jim not praising an old fashion platformer and warning people over performamce issues he experienced. If he experienced choppy framerate, he can't just pretend it didn't happen. That would be stupid.
What platform did he experience these issues on, how bad were they, and was the performance the only problem he had with it? He could properly answer these questions after the embargo, but instead we're just left with a 17-page thread urging people to cancel preorders based on the most vague of comments.
