Sigh. Jesus, this is Star Wars Episode I all over again. Hyped up to holy hell, even though it was never going to live up to expectations. I know the game has some problems, but not to the point where it ruins the series.
Although Episode 1 is an apt comparison. A film that, over the course of 13 years or so, was derided and ripped apart by critic and audience alike. The consensus was that it wasn't very good at all. Then the re-release (in redundant 3D!) came along and made 50 million dollars theatrically.
To me, you can't polish a turd, and that's all this re-release is attempting IMO, just like Episode 1. If you're looking forward to it, who am I too deny you that? But it would take more than a makeover to make Doom 3 sing - it would take an entirely new game.
