I'm casually interested in this thing, simply because Atari doesn't really have any memorable nostalgia characters to fall back on for first-party games. Third-party games are a huge plus, but first-party games sell consoles. Nintendo, Sony, and Microsoft all have hugely popular characters that they rely on to sell millions of games, whether the games are good are not, and it's gotten old (looking squarely at you, Metroid Prime Federation Force). Because of the lack of nostalgia characters, Atari really needs to bring their A game when making first-party games or they'll go out of business, which means, theoretically, we're either going to see some amazing games, or we're going to watch the company self-destruct.
I'm really hoping this console can put some pressure on the big 3 to stop releasing crap just to cash in some nostalgia bucks.
