If you are making a game and it is good but doesn't sell, at a minimum you have something in your resume/project list that you can control that helps your own personal product. Then you can use that project to get contracts, clients or other funding/income to help fund games or products. Finishing and publishing a good game that you enjoy is never a waste of time. Finishing anything, making products, and launching them on your own is a great skill to have, very desired in the market, shipping many games is even better. But I agree, go in with the assumption that the game may actually lose money in terms of time put in to revenues. Direct revenues of the current title is short-term thinking on something that can help long-term in other ways.
