...for not being a game.
I have no interest in shooting monsters or people, or defeating the boss to get to the next level. If I'm going to fill my muscle memory with anything, it will be "Pavane pour une Infante Défunte," not how to get through a maze, thank you very much.
I like Second Life as it is; like Real Life, it's what you make of it. Any goals are your goals, not those someone else has decided to impose on you.
