Didn't Capcom have a rule that over 80% of their output HAD to be sequels, and games like Lost Planet and Dead Rising were practically made in secret as a result?
I don't think the video game industry is nearly as different from films as we'd all like to believe. While it may not be a "franchise", video games chase after Call of Duty and Warcraft and whatever was once successful and copy and copy and copy it until it runs out of copy paper.
And we've remade/rebooted probably just as many games as movies, if not more. Reboots and remakes of Syndicate, Tomb Raider, Metal Gear Solid, Resident Evil, Mortal Kombat, Shadowrun, Zelda games, etc. Hell, the VAST majority of titles for current gen systems are mostly last-gen titled dolled up on new machines and released at a premium (Sleeping Dogs, Tomb Raider, Grand Theft Auto V, Saints Row IV, Injustice, The Last of Us, Diablo III, Minecraft, Metro Redux, etc.)
Microsoft's "big fall/winter release" is just re-releasing the old Halo games with new visuals. Their banking their holiday season heavily on games over a DECADE old because it's a safe, easy, reliable way to make money.
Movies aren't any different, but that's also not fair to the many fantastic, original films that come out that so many people don't bother to go see because Transformers Whatever makes a ton more money. That doesn't diminish the fact that movies like Snowpiercer, Birdman, Fury, or John Wick are amazing in their own right.
Of course I want to see more new (GOOD) IPs. I very much enjoyed that odd "golden year" where EA developed a conscience and gave us new, brilliant IPs like Brutal Legend, Mirror's Edge, Dead Space, Army of Two, Dragon Age: Origins, Bulletstorm, and Shadows of the Damned in short succession. I would love them to keep that up, even as I acknowledge that they have, begrudgingly, done so with Titanfall.
So, yeah, I think video games are becoming more like films in the way their business is handled. Focus groups, market testing, zombies and guns ruling the landscape. I don't think it's going to get "better", but that's what the indies are for.
