Now, looking tough the net I found myself o Diablo 3 site and then I got a brilliant idea. Why FFG would not do a Diablo board game? They have the rights to Starcraft and Warcraft so why not Diablo? This would be a bestseller. There are many fans of board games and the Diablo title.
This should be something big like a crossover of Descent and Middle-earth Quest with elements from a RPG games. So You would have Exp points and so on. A game from 2 to 5 or 6 players. With a amazing huge map, minis, tokens and all the great extra stuff. With lots of fluff and more. Now I think this would be a huge sucess. And one of the best titles in FFG library.
Or they could do a RPG game or bettes bought.
