Some, but certainly not ones that are trying to hard to be labeled art to be immune from criticism (ex. Psychonauts or Braid). I think Mass Effect is the gaming equivalent of art. I think Ninja Gaiden 2 could be counted as art. I also think Gears/Gears 2 can be counted as art. All for different reasons, but I don't think silly visuals (ex. Psychonauts or Braid) or the setting determine art, I feel things like story, or visuals (again, not ones that TRY to use the art excuse to render themselves immune to criticism) or music, or when you know quality went into making it. Hard to explain sort of but miracleofsound has the right idea.
