While yes, games can be consumed purely as an activity, in a lot of cases games made me feel something more... such as the sense of wonder, or feeling immersed on it, or admiring the whole thing as some sort of interactive play and wondering what was the creative process behind it. And I'm not necessarily talking about deeper or more complex games, I felt this sort of stuff even with old ass Atari games!I don't think they can be art. Don't get me wrong: it's not that I consider them to be inferior than other human artifacts, it's just that they do something different. Aristotle made a relevant distinction between primary arts and secondary ones, and that distinction can be seen in, for example, eroticism and pornography: the first one implies contemplation, while the second one... Well, you now what happens: it makes you want to participate. And that applies to videogames: they don't favour contemplation nor any inner exploration: we lost ourselves inside them, and they take control.
I can admire a brainless kaiju movie for the effort they put into the costumes and scenario, or a puppet theatre for children for that matter. The same way I can admire a gorgeous character sprite that isn't trying to convey any deeper meaning, and I know for a fact people don't hesitate calling pixel art, well, art.
The fact something was made primary for engagement, doesn't mean you can't take your time admire all its layers, or to feel wonder by it. If something made you feel that, then there probably was artistic skill and/or human expression behind it!

My view applies to pornography as well. I could even make a point that certain specific works overlaps eroticism and pornography.
There is an distinction I make, however: was it made with passion or purely for money? There are plenty talented artists that likes to draw pornography out of passion. On the live-action medium, on the other hand, you can tell the actors are just doing their job.
