me and my friend are starting work on our game. The goal is to use this project on our resumes as well
When it comes to "experience" on a resume, it means paid professional work experience, not stuff you did on your own.
If you have a section of your resume devoted to your hobby project where you and your friends built something, and that something did not end up being a commercial success, what you've got doesn't really count except to show interest in the field.
Now if your side project gets a million downloads and becomes a major success, then things are a little different. Then you are an entrepreneur who successfully started your own business, and the experience looks great. Statistically that is unlikely to happen.
I don't know if its quite so harsh as that. Hiring for a junior or entry-level position, I would assume most companies would expect to find programs from college coursework or interesting hobby projects under the headline of experience. That's certainly what I'd done with my own resume years ago. I concede that one should aim to eject these "experiences" from one's resume with professional experiences as quickly as they are able after some time in the workforce, though. For myself, having taken some non-games job fresh out of school, it was a few jobs down the line before further expansion of strictly-professional experience was more prudent than to include some of my non-professional, but games-related experience.
In general, prefer professional experiences, but bubble up interesting, relevent non-professional experiences/achievements over uninteresting or irrelevant professional experiences. Within a few years or few jobs, you'll have enough varied professional experiences that you'll only be tempted to include non-professional experiences that are truly stand-out -- if you find that this is not the case after several years or jobs, then you probably have had a problem setting career goals and directing your career trajectory.
