Besides Dark Souls (which I have no interest in playing) I can't think of any recent releases that focused on one core audienece. Practically every AAA game released this year has went the 'appeal to everyone' route in favor of playing it safe and focusing on it's core audience.
Franchises that started out aiming at one core audience eventually devolved into a 'jack of all trades, something for everybody' game instead of sticking to their roots making subtle tweaks. It's to the point where the bigger the hype for the game is, the more I expect it to disappoint.
I even remember reading an article on gamespot that Dark Souls devs were consdiering toning down the difficulty. I think variety is a good thing and not every thing created needs to 'mix it up' and focus on appealing to everyone. Why not just create new IP's instead of reinventing something with hopes of attracting new players? Money and politics is the answer I suppose but it minimizes my excitement for new releases fearing they will all be 'jack of all trades' type of games.
