The classic Mac/Windows game DEFCON is still available on Steam. Its combination of vector graphics and an eerie soundtrack are still a good but sobering experience.
I think the vector graphics are inspired on the WOPR computer from the film WarGames.
btw, that movie has a sequel which is probably the worst sequel of any film ever made.
Now... nuclear war strategies will change now that there are hypersonic missiles and scramjet vehicles.
