This videogame reskins it with The Horus Heresy, a prequel setting 10,000 years in 40K's past that's been the basis for a huge amount of novels, some of which are actually quite good. It was fantasy Snakes & Ladders with PvP.
Even if the other players didn't drag you down, the luck of the cards and dice would. It was a race-to-the-center board game, half of which you spent finding a talisman to let you access the middle of the board, and the other half not letting someone else steal it from you.
Games Workshop released the first version of Talisman: The Magical Quest Game in 1983.
