I am trying to install Wolfenstein for PC on my Vista PC. But due to inadequate RAM it was not working. After adding a 2GB stick the game is now working fine without any error. Now I was just testing a 3D game will work on my PC or not .For that Return to Castle Wolfenstein is a best choice. I will like to try some level plays before that. How to being this one now and what is the entire game about.
