Pick Command & Conquer: Red Alert. Developed by Westwood Studios - whose seminal Dune II created the real-time strategy category, and whose Command & Conquer (along with Blizzard's Warcraft II) represents the highest achievement in the genre to date - Red Alert has the pedigree of a champion and a premise to match: Albert Einstein applies his theories of relativity to time travel, hurtling back in time to assassinate Hitler before he ever comes to power. The plan works, and with Hitler out of the picture, Nazi Germany never materializes. But unfortunately, the Red Menace does, with Russia's Stalin turning a burgeoning war machine towards the West, raining destruction and terror on those unfortunate enough to find themselves standing in his way.
