There is a significant difference between a locked-at-30fps game and a locked-at-60fps game. Heck, I've seen 60fps video on a PC and you could instantly tell that it was uncannily smooth compared to regular 30fps video. Many high-end filmmakers have been pushing for higher framerate movies as well - Roger Ebert has been a big proponent of this due to demos he's seen (preferring it over 3D), and James Cameron was pushing for Avatar to be filmed at 60fps. One of the most interesting examples of 30fps vs. 60fps. was the PC port of the original Halo. It has the option to unlock the framerate from 30fps and render as fast as possible, unlike the locked-at-30 Xbox original. However, all the animations were 30hz - if you disabled the framerate lock, the gameworld would run perfectly smooth (moving, physics, etc.), but all of the animations stayed at 30hz, appearing choppy and disconcerting. (I believe there are demos of Halo 1 for PC and Mac, should you have a computer capable of running it - since it's many years old it should be OK on anything with a reasonable graphics card, though you may need to turn the graphics settings all the way down to see the effects.) Many games will be fine at 30FPS, as long as they maintain that framerate - but for very fast action games, the extra frames do make a noticeable difference in feel and responsiveness.
