The industry needs innovation, otherwise gaming becomes stagnant and incredibly boring, much like it is now.
However, the problem with innovation is that no big company is willing to risk the financial loss to generate a AAA title that brings something new to the table, they have the capital, but not the willingness to do it.
On the other hand, Indie developers have the willingness, but not the cash.
Evolution and innovation needs to happen in the industry, thing is, when innovation comes about and it becomes successful, everyone copy/pastes the idea until it becomes boring and stale again, I've always thought that huge companies like EA and Activision should adopt Indie subsidiaries, give them the money to work, but let them do things their way, that way, we get a hell of a lot of new material, evolution and innovation comes about and the media as a whole becomes a hell of a lot less stagnant.
We'd get a few new IPs out of the whole thing too, I mean...You look at the industry as of late, pretty much all the big, hyped up, AAA releases are all sequels, even looking at my game catalogue on my laptop, it's 90% games with some number tacked on the end and it's a little boring.
Reusing characters solely because they're successful is just lazy, take Mario for instance, look at that little bastard's games, there is very little in the way of innovation or evolution in the Mario games, and yet people still buy them, it's a sad state of affairs because eventually they'll screw up the entire thing until it needs to be taken out back, Old Yeller style and have it's brains blown out.
Which brings me to my final example, Sonic the god damn Hedgehog, you look at what happened there, a well known, well loved series reduced to...What? Crap, in short, just because they were scraping the bottom of the barrel for ideas.
Innovation is great, but so are new IPs, you can only bring so many new game designs and mechanics to one series before it begins to get stale, we need evolution and innovation not only in existing, established series', but we also need it in the development office in general, we need more companies to come forward and go "No, no more carbon copies of Generic-FPS-A/B/C, let's make something ENTIRELY different!"
/my two cents.
