There is a large number of free qualify fonts available at fonts.google.com, many of them are free for commercial use outside the web. There is also a handful of pretty good fonts not included in that collection but also freely available. (This is on top of good collections of fonts shipped with major OSes.)

There is a number of free fonts which are also free for commercial use, but are clearly inadequate for serious typographic work, or only contain highly stylized glyphs. They may still be perfectly usable for a game, or a mobile app which is not typography-heavy. In many cases, the shortcomings are only visible at paper resolution, or only in print as opposed to screen.

Then, there is a number of not very expensive fonts that cost $50-100 per face. If you really badly need a font exactly like that for a commercial project, and $200-300 is a prohibitively expensive for a permanent license you obtain, how much is the commercial project worth? Is it worth sweating over that very particular font?
