Good, that's what I advocated many years ago (even wrote an article about it). For most games a solid 30 FPS is more than enough to provide a silky smooth gaming experience. If not smooth enough in cases (like specific parts of a game) adding motion blur would help more than a higher framerate.
Framerate merely has to do animations being fluent or not for human perception. Less than 16 frames per second can cause problems depending on the game, 24 frames per second has for a long time been the standard for hollywood movies.
Many cartoons on TV are only 6-8 frames per second.
