What is a game? I would say that a game is an abstract system used to understand our reality (or experiences in life), via a series of interactive actions that alter the system. Generally there is a set of goals (usually just to "win").
I develop software because it's a game. I do watch a lot of progress bars. Aside from that, it's one of my favorite games (to my wife's chagrin). It's fun for me and I'm not the only one. Why does it matter that other people don't enjoy what they do?
