I'm making video games for PC, Mac and Linux (like this one - http://store.steampowered.com/app/386900), it's a very traditional release cycle, I work on a project for x months, and then I release it, moving onto the next game after a few weeks of post-launch support. PC games are generally seen as more valuable than mobile games, so I don't need to sell a terribly large volume in order for me, a single developer, to make a living.
