Hmm, I think you downplayed Star Wars' influence there. It's the space battles too. If the sodding Matrix can get in this list Star Wars has to - not just 'lightsabers'.
1984 is what I believe to be the most influential nowadays, with all these dystopian (which my computer doesn't believe to be a word) future games. Not that there is a reoccurring overruling government, but it's not uncommon.
