Can games move you? Can games have a distinct, emotional affect on an individual who plays and experiences them? Then they're art.
In my opinion, one of the only definite characteristics that we can apply to all things considered art - painting, architecture, film, music, literature - is that they are considered art because of the impact they have on the people that consume them. These works stay with their audience, one of the central reasons people write about, discuss, and praise them. I'm sure that every single person on this website has played a video game which has really "stuck with them", or really moved them in some way. That is affect, and affect is what good art is all about.
