Again, there is no "choosing". You can choose both if you really think they apply. And again, maybe "artistic" isn't the right word for how it's used right now, but if you're making a game that you want to be commercially viable you probably aren't making Mu Cartographer or Strawberry Cubes or Slap Game. It's not "Oh all these commercial games are so soulless and unartistic" but the goal of making a commercial game is in line with the status quo of how people expect to be entertained and get enjoyment, while the games that, by more traditional definitions, are being made "for the art of it" are generally so far removed from that goal, and these two things are absolutely choking each other out.
What would be the alternative? Just make a "commercial games" category and everything else is just everything else? What word would you use to describe "games that are trying to experiment with the medium, not entertain you"?
