If that were true, you'd see a lot more development companies staying alive and not struggling. Sega, for one, has made some excellent games like Binary Domain, Vanquish (well, published), and more. Then why did those games sell like ass compared to stuff like Madden?
Shenmue is a niche series that did well the first run, but once again, could it survive in this climate? It's a slow-moving action game with a lot of story. You think it'll do good in this generation, especially after you have the faster-paced Yakuza?
And you guys need to stop saying that it will outsell Yakuza when that game has been long since established. The fanboy-ing is ruining this topic.
