I think the only reason for frame rates of 30 or 60 fps is the american analog television system NTSC (approximately 29.97 FPS).
Perhaps most game developers thought that if 30 FPS is fast enough for television, it also must be fast enough for video games. Later when the graphic cards became faster they doubled the frame rate to 60 FPS.
