Unfortunately this is not true. Modern AAA franchises do not innovate. They are just shinier. You can find the same systems, and often more complex or creative ones, in games from the nineties and 2000's as you can today. Modern gamers either become jaded, seek out indie games, or, more often, simply buy what is offered.
Remember when the big question used to be "are video games art? CAN they ever be art?" I remember publications like PC Gamer spending a lot of time and energy wrestling with these questions. It wasn't lip service; it was a real goal that game creators at the time pushed towards, because gaming was trying to find acceptance and respect alongside other forms of media. I think that has mostly been lost, now. There is and will always be indie creators pushing their own creations that are inspired, but the AAA market is totally lost, imo, if you are interested in games as more than just a mindless bit of fun. That overarching sense of progressing towards something that could be considered true "art", is gone, for the time being.
edit: didn't mean to sound like I wasn't giving credit to all the fine indie games and game creators out there. There's still artistic and interesting things being created, just not by AAA studios :)
