Take XCOM: An excellent game. And not not intended for modding. But I freely admit to having modded my game, because I, personally, think this improves the game. Of course I cannot use my own personal, subjective preferences when competing against a random person online. But then, I never wanted to play XCOM as a multiplayer game and indeed, did not even know it had multiplayer until after I received the game as a gift from my girl. Multiplayer was neither selling point nor a manner in which I wished to play the game and so I feel that, as an owner of the title, it is my right to play the game in whatever manner - and state - I prefer. Shoehorned multiplayer modes that no one wants to play, and the perspective that they themselves own the game, are excuses used by large publishers to explain away their attempts to rob gamers of their rights not only as consumers and owners of digital media, but even as players of a given game.
