The Return to Castle Wolfenstein thread got me thinking about the first fun action PC game I ever played, a little snippet of an executable called simply Castle. It was graphics in the crudest sense of the word. It used the 40 column mode of the old IBM CGA display with an assortment of upper order and graphic characters for the player and ogres, monsters, snakes and vampires that inhabited the castle. you could only fight enemies by bumping into them repeatedly. Sometimes they killed you but somtimes you killed them, especially if you had picked up a weapon or charm. I miss the good old days when 256k RAM was what you had after and upgrade.
