One of the issues with games not being accepted as art is that their too much fun. Take movies for instance; there are a lot of films out there that are not particularly entertaining but are nonetheless critically and commercially successful. Schindlers List is not especially fun to sit through but because it conveys a powerful message and is well crafted, people accept it. Novels too are often not pure entertainment. Games on the other hand will always sacrifice message for fun. War games can be as serious and reflective but it still has to be fun to frag bad guys or the game will bomb commercially and critically. Reviews always put the emphasis on "was this game fun to play" and not on story or the power of its message. Say a publisher decided to release about genocide, or any number of meaty topics, and the games tone did not allow it to be fun or action packed. Say it was a Holocaust game where you control a Nazi officer given orders to murder jews in a death camp. It could be a powerful game even more powerful than a movie because the player pulls the trigger, but it would not be fun. It would be uncomfortable and depressing. Would you buy a game like this? Would you buy a game that is not fun because it was powerful art? You'd watch the movie, or read the novel, but would you play the game?
