Wait... who wants to make the game into something it's not meant to be by modifying the game into something it is not?Thats a misconstrued and stereotypical assumption that a casual player would want to believe, but has been shown why it's wrong time and time again. I want something because it enhances the game and takes away detrimental things like not being able to see people from a distance. If it bother's you so much, YOU have the option to turn it off. I don't really see why artwork on the wall or why the way some character looks in a game, that stresses player interaction and skill, matters so much in "entertainment" value other than you're wanting the game to be something it's not meant to be. If competetive games aren't good for public, then we wouldn't have any casual players at all as any popular competetive game has a majority share of casual players to begin with. And competition has almost always been proportional to a games popularity, atleast in games that pit players against one another. Though I'd love for you to share some titles that say the oppposite.
It's not misconstrued and has never been shown to be false. Almost every game that has a large competition base was, by and large, NOT made for competitive play and is most commonly modded to be appropriate for competitive play. Look at Q3A. Without CPM, it's not even really suitable for competitive play.
Games that are made for competitive play are almost never very good casual games (see Warsow, and, frankly, even UT2003). The two play styles don't really work together, they are mutually exclusive.
I also think it's funny you mention the player interaction and skill and yet are defending something that emphasizes simplifying (def. to make easier) certain aspects of the game. WEEEEE!
