Gaf has a ton of diehard Metroid fans, me included. As of right now, the Fed Force review thread has 4 pages, the Fed Force ending thread has 4 pages, and the thread for people who bought and are playing the game (the OT)... just made it to two. Two pages.
That tells me loud and clear that no one is going to buy this game.
This was my thought yesterday too. When the OT was still on page 1 halfway through the day, I thought there might have been some sort of inventory issue where Nintendo shipped so few games people were having trouble finding a copy.
