Video Game Making Software - Reality Factory - Create First Person Shooting (FPS) Games for Free

As you can see from the video Reality Factory is software for students beginning to get serious about pursuing game creation.

The software is very powerful given that it is free. It has forum support and many online tutorials.

NB I have used Reality Factory with of my senior computer classes but set the stipulation that no 'living' organisms were to be harmed in the gameplay. The 'opponents' had to be something like mutant teddy bears or out of control robots. They coped!

Here is a Reality Factory tutorial I used to introduce the program's interface.
