Risk
A terrible, terrible board game of napoleonic world conquest where you move around tiny plastic soldiers and cannons and pretend you're making any sort of strategic choices. All your fate depends on dice rolls and how soon you manage to hog the best territories.
There have been many versions of Risk made, including future Risk.
Also, the 40k Dawn of War games Dark crusade and Soulstorm impliment the same structure but instead of a territory being detemined by 1-4 dicerolls, is determined by a 40 minute game of 40k, needless to say, its much better
