My dad (who is 58) has never played games before, but he bought a blu-ray player that streams Netflix so poorly that I convinced him to get a PS3 instead. To my shock and awe he is even considering buying some games. He likes sci-fi and action movies, loves to read, loves gadgets and tech stuff, but has NEVER played ANY video games. I'm looking for a "gateway" game that will give him a good introduction. Any suggestions?
