If it is any confort I do not use STAR approaches as I have yet to learn how to. With FS's ATC you would be instructed to climb (rather than vectored around) and, quite often, then given landing instructions from a ridiculously high point with the runway almost under your toes. I do not think any add-on ATC is able to read the terrain files to know where mountains are - for all the pleasures of PF3 there have to be some sacrifices too.It's all very well to say that ATS only takes into account course directions but that's not strictly true is it? They instruct you as to the altitude for the whole flight and have to take into account the altitude of the airport, otherwise they couldn't give the instructions to get you down to the right height for eventual landing. Personally, I think the vectoring was wrong and they should have got me over the sides of the valley from further out at say, 12000' and then brought me down along the valley.
Furthemore, if I hadn't obeyed ATC, they would have nagged and nagged and then withdrawn their services as has happened to me before!

If you have FS Navigator or its FSX equivalent you get a basic representation of the terrain (from screenshots the FSX one may be better). I don't know what scale the figures are (in fact I am quite mystified) but I add 50% to the given figures and keep at that height until clear and I seem to survive.
As to nagging and withdrawing services - there is a mod available for FS's ATC that stops this. But surely you are talking PF3? Nagging can be reduced - you can set the frequency of nags. But you can also request an altitude change, which seems to keep ATC happy. Finally, I have never had ATC services withdrawn by PF3 (not even when I fly off in the opposite direction to lose height) but you can request "cleared to finals at pilots discretion" which means you will hear nothing from ATC until you contact the tower.
