At the end of the day, game development is all about people [besides making money]: You spend most of your days working with a team, which becomes sort of a family. There are great times and times when you all struggle to work out the differences and ship the game. You connect with other developers on social networks. Go to events and jams. Build a community. Market your game. Your game talks to players and they talk back. It makes them happy, angry, sad. And players talk about your game to other people.
