Question: do u need to play demon souls before dark souls and how long are they
Answer: You don't need to play Demon's Souls to play Dark Souls. The plots of the games stand on their own. The games take about 50 - 100 hours to complete, depending on how much side stuff you do and how much you die, considering that the game is relentlessly hard.
