Hudson Entertainment got bought out by Konami and closed the North American office in late March 2011. Konami is presumably hosting this sale to "get 'Bomberman Dojo' and other titles at discounted prices." Bomberman Dojo Knights of the Phantom Castle Rooms: The Main Building Maybe more will come up. I highly recommend Knights of the Phantom Castle.
I picked up Bomberman Dojo. It's not quite what I expected it to be. I wonder if they're going to put the other Bomberman's on sale too.
I was thinking of picking it up on sale, too. I'm curious; how is it different from what you'd expected, and do you like it?
