Depends. A game of checkers on "Windows games" can reach 1 frame per second and I won't care. Why? Because the pieces moves...in one frame. So it won't make much of a difference.
Now, let's say you're playing a game such as Professor Layton or Phoenix Wright. I won't really care if it's 30 or 60, as either way the difference won't be that big.
Concerning games such as Xenoblade, Halo, and so on, I don't see why they should be below 30. All intense games should aim for 60 fps(or 30 fps locked. Consistency matters most).
I've never cared much for framerate. It's only when it's to the point where it feels like the images are stuttering when I'll say something about it.
