It doesn't really matter if you're in the industry, so stop holding the appeal to authority fallacies up in the air. Rockstar is one out of a very selected few developers who have carved out and earned a degree of autonomy (others include probably Blizzard and Bungie and very few else) despite being corporately owned; and perhaps ironically, their next title is GTAV.
I don't know why you even mentioned 2K, who are in fact named for their previous annual sports franchises, and indeed release almost nothing but franchised titles (recently Bioshock/X-COM/Sid Meier/Spec Ops/Borderlands/etc). I assume you meant Take-Two, since they own Rockstar and 2K.
If you're so sure of what you're saying about the industry, why don't you google up a link of 10 best-selling titles for this year to date and tell me which ones are new IPs? I'm guessing probably The Last of Us, and that's all. I'm not even gonna look myself, I have no idea what the numbers are. You get to tell me which ones are new IPs and provide the link, and we'll see what is actually making money now. While we're at it, pull up the past few years, it should be interesting. You can pull up the top 10 box office as well, if you're feeling ornery; prove me wrong.
So we're clear, I'm not saying it's healthy for this focus to continue. It's unhealthy creatively, like i said in my last post. But if you really don't believe that's how it is now business-wise, you are fooling yourself. It's a fact. You don't have to like it (I don't), but the entertainment industry is creatively bankrupt right now.
Don't even know how to respond to this. I guess lol would be appropriate.
