I saw a lot of FPS Game creating software topics in the FPS thread. But what I want is a 3rd person game making software. What I want to make is something like Prince of Persia or some medieval game. It must not be first person. I want it to be 3rd person. I couldn't find a good 3rd person game creator.

I did see some softwares in many websites but I don't know whether they are good. I tried Game Maker Pro 7, but you can only make crappy doom 1 style games from it. I want some thing with much more flexibility where you can work in an 3d environment and apply shadows and physics. If I can import 3D objects from 3D MAX files or MAYA files hat is even better. In Game maker pro there is only a 2D environment.

If anyone knows a software like what I have mentioned above, please do not hesitate to post

Not really, it is a case of learning it all. As far as I know, Gamemaker is appalling, but the best there is.
