Well, that depends on how we're coming at the game, doesn't it?
The primary focus of art, of any medium, is to evoke emotion. That's really it. I mean that's your most basic, go-to definition. I mean, as many have said in this thread, the art world has face-fucked this definition into the fucking dirt with rubes and a tool for millionaires to move their assets around like poker chips. But essentially, art's purpose is to evoke emotion. Simple or complex. That's really it, when you boil it down. That's all art ever really is, something that evokes emotion. We can then judge it on how well it evokes emotion, if it actually is, or if its a bunch of fucking idiots fawning over nothing. A lot of times, lets be honest, its the latter. Especially in today's art world.
Basically, everyone is Ongo Gablogian:
Can games be emotive? Certainly. Can they capture the human condition in a narrative way, comparable to literature, movies or comics? Ehh, that's a much deeper question. And it really depends on you. That's really the whole thing with games, isn't it? Art is subjective. Gaming is EXTREMELY subjective, because by its very nature, we all play it differently. Therefore we're each going to get a different experience. Hence, some of us will never experience a game as art. We'll never find a game as evocative as a movie, a book, art, or anything else. Alternatively, many of us will experience things that are MORE emotive, even if the stories and narratives are simpler, less complex or worse because we control it. Its an extremely active form of art.
So sure, games can be art. But they're highly subjective because we all play differently. Which is why the question is contested, but at the end of the day, it doesn't really matter. Enjoy what you enjoy. If you find them artistic and love dissecting them, go ahead. If you just want to be Geralt and fuck a hot redhead and dissect monsters, do that. At the end of the day, enjoy yourself. Too many people these days try to suck the enjoyment out of everything. And don't justify these things to yourself. Enjoy what you enjoy.
