I typically shoot for 60 as my goal. That usually gives you plenty of room to work with. Of course, any more than that is great too.

hmmm this is suprising to me. I'd think Flightsims would need a lot more than that as there is more precise control required.

Yes they do, esp. while landing e.g..

But flightsim motion is smooth in contrast to non-physical motion in most FPS. So motion and opponents motion are anticipatable (does that word exist??). And view cannot change that quickly. In Quake, you can turn by 180° in between 2 frames....

This all reduces the needs for framerate.

RTS play well even with 10fps I think.

I too shoot for 60fps but have found you can get away with 30fps for slower machines without it looking too bad. It does depend on the amount of change going on between frames - if you're not smooth scrolling, and if all your animations are are 10Hz anyway, then 10FPS is enough (but make sure you use a hardware mouse cursor and buffered input to maintain the illusion of a smooth interface).
