You have to be careful with freeware fonts, especially if you're going to be using them for body text or at small sizes. A LOT of work goes into making a good font. Not just the design of the actual glyphs, but the hand-kerning of thousands of individual pairs, autohinting, ligatures, and other exotic things like that. Some freeware font authors do a sloppy or non-existent job in those areas. Though of course there are high quality freeware fonts as well. You just have to be careful, and be prepared for some trial and error, that's all.
If you have even just a modest budget, you can consider looking into paid fonts, that you know will be guaranteed to look good in all situations. Some fonts cost many hundreds of dollars, but not all. For example, Futura Medium Condensed, which is the font that Skyrim uses, can be had for about $30.
