I don't agree, but I can understand the sentiment. It used to be that games were pleasantly simple and each trip to the video store meant coming back with an new gem to polish off over the weekend. Having been born in 1983, my memories of the eighties are a tad hazy. I do remember owning a NES and playing stuff like the Mario-Duck Hunt combo cartridge, and moving on from there. I grew passionate about gaming in the nineties, however. Prior to that, despite having an NES with a metric fuckton of games for it, I was much more of a bookworm. Considering, I don't hold platforming as being anything special, but I do have pleasant memories associated with it.
I really got into the scene with PC gaming. Myst was my first digital addiction and Half-Life became the first title I'd be interested in replaying over and over. From the point of view of pure mechanics, what draws me into gaming is still there. There's still engaging gameplay, and with the average player age progressing, ludonarrative pairings are getting more and more intricate. If you'd told my 1989 self about Uncharted and how I'm purely driven forward thanks to the story (I swear that series feels like a set of controller-based page-turners), 1989-me wouldn't have believed you.
Games have more potential than ever before. What's changing is who is actually tapping into it. It used to be you could depend on Electronic Arts or Sierra to dish out innovative and interesting titles. It used to be Broderbund was a publishing goliath and even took its chance with the Red Orb publishing subset. It used to be that AAA gaming was synonymous with innovation. Not anymore, and that's not necessarily a bad thing.
Innovation is now the hallmark of indies. AAA studios are too busy surviving and catering to the lowest common denominator to muster the same level of passion as before. Today, you're not supposed to be passionate about games as a whole, they'd like you to be passionate about a *franchise*.
The trick to preventing this from crushing you and making you feel alienated is to pay attention to both sides of the coin. Keep an eye on AAA releases, but also keep up on your favourite indie studios. On occasion, you'll realize that someone managed to slip an innovative mechanic into Generic Brown FPS no. 46, or that an indie is taking pages from the mainstream and re-interpreting them.
Stay on the lookout, OP. Don't get bogged down by the yearly crop of samey releases, you're not their intended target! Considering that, why even care? Why be bothered by this? Let the CoD-craving masses have their fun, knowing there's plenty of avenues for you to have your own.
This isn't exclusive to games, either. Take books, for instance. The best-sellers are inherently going to be crowd-pleasers, and that means tendencies are going to surface. We're saddled with supernatural romances galore and poorly written teenybopper wish-fulfillment vehicles - but that doesn't mean that's all there is to the mainstream.
Plus, if you're seriously desperate, who's going to judge you if you decide that your light reading for the summer's going to be Anna Karenina or The Count of Monte Cristo?
Games are like books. Going back to the classics on occasion can rejuvenate your gaming spirit, if there's such a thing.
So you're fed up? Tired? Boot up your old NES or the Wii's Virtual Console, and have a go at something that's really distant from the current gaming industry. I guarantee you'll come out of the experience feeling renewed and ready to try out what else the AAA market might throw at you - knowing that market operates exactly like the mainstream Genre Fiction deluge that's piling up at your local bookstore.
Nobody's asking you to like it - but keeping an open mind can be useful.
