Think of this as an opportunity to learn how to deal with things you don't particularly want to do. If you walk away because it's draining, when are you ever going to not walk away? How will you know the difference between something you should walk away from and something you should stick through? If it's truly making you miserable or you have a better opportunity lined up, then by all means. But I think first making a more refined distinction about what the problem is will be more useful to you, even if you do eventually decide to leave. Is it the company or the project? Is it the technology or the fact that you're picking up a project someone else already started? Is it the work itself or the expectations and constraints involved? Do you have the power to set or change those constraints to make the project better for you? Can you get that power or authority? Can you, personally, ask for it in lieu of quitting? There will always be some things you can't change, but you should always look for things that you can. Also, regarding passion: reading HN and being 19 are both great ways to get an exaggerated notion of the importance of passion. You don't have to care about games to be highly engaged in the creation of something that happens to be a game. It helps, I'm sure, but your job isn't the like the game, but to like the work. The verb is the work. And if you need something to be passionate about, try answering the ever-evolving question: "How can you do your best work, given the constraints?"
