As for the question if it would still be good the second time around? Of course! I still whip out my sixty-four and give it a run through from time to time.
I really like the HD versions of games they release for download on places like XBLA. The HD version of Perfect Dark (Goldeneye's spiritual sequel) is fantastic. It is great to go back and play it again looking smooth on a widescreen HDTV. If that was what was coming to the Wii, I'd feel some excitement. As it is, it is just another crappy Bond liscensed game trying to capitalize on the popularity of the one James Bond game that really made it big. The title is the only thing that has everyone all worked up. If it was just another Jame Bond title, it wouldn't even have its own thread here.
While it may be based off of and titled after the same movie as that classic 64 game we know and love, it wasn't the title or the story that made that game great, it was something more than that. And the something more than that, I can almost promise will be lacking from this game.
Whether it is a good game or not, is yet to be seen. But trust me, this isn't our Goldeneye.
