There are a lot of phenomenal indie games. There also are still a couple of really good AAA games, but AAA gaming isn't what it used to mean. In fact I'd be careful with AAA by default unless reviews state that the game is actually good. Ubisoft even tried to establish an "AAAA quality" game with Skulls & Bones or how it's called and it's a total flop.

The real quality these days lies in indie games or (mostly) independent gaming studios. I think it's kind of safe at this point to just assume by default that Bethesda, Microsoft, EA, Activision-Blizzard and so on simply cannot produce actual good games anymore (there may be some exceptions, but again, wait for independent reviews, and unless it was independently verified, don't trust them to produce a good game).

Another problem is the sheer mass of games flooding the market, because it means that true gems aren't found so easily. But they exist. There's no shortage of great games, you just have to look harder, and look in the right places.
