GAME CUBE ROCKS. THAT IS ALL.
The demise of games consoles is pretty interesting. The Atari Lynx did extremely poorly, because of lack of games and because it was a poor design, so Atari abandonded it and started focusing on the Jaguar. Then the Jaguar did extremely poorly, because of lack of games and because the controller was an abomination, so it abandoned the console market altogether. The Sega consoles were always a long way behind the equivalent Nintendos in terms of sales, and therefore in terms of games as well; a similar pattern to Jaguar's demise was followed by Sega. The Saturn did poorly, so they focused on the Dreamcast. Both failed because of lack of games. I'd argue that the Dreampants also failed because the controller was too big and ugly.
THAT IS ALL.
