this and Sphinx are the next console games I plan on getting after I play through Metal Gear about 4 times and finish the 10 GBA RPG's that I have gotten in he past two months(Golden Sun, now its time for some Lost Age, boktai , and some FFTA)
my main reason for not getting it was gamestops buy 2 get one free pre-owned deal. I literally cleaned house, and since then I have been trying to finish these before I move on and get these games.
Also I think that if sphinx and BG&E were GCN exclusives they would have sold through the roof. Personally I own very few non exclusives games for any system I have. Its not that I dislike 3rd party games, its that one title always gets the shaft, so I would rather support the people who focus on making a title for one platform and making it the best title they can.
