Research on navigation: Your advice please!

Hi,

My laboratory studies the brain regions underlying spatial orientation and navigation.
I am interested in running subjects through simple virtual/game mazes on a PC.

This would be a basic navigation task like in Doom/Wolfenstien with doors, hallways and a few objects.

I need something that will provide information on the location of the subject, time it took them to complete the task, length of the route they took and errors (opening the wrong door, or going down a blind alley).

I have some experience programing in C-shell and Python but not much more...

Any advise regarding appropriate PC software would be highly appreciated!

thanks much!
