Dark Souls is very much the successor to the Playstation 3 game
Demon's Souls, whereas Demon's Souls was exclusively for the
PS3 Dark Souls is also available for the
Xbox360.
Demon's Souls was well none for its high difficulty, but Dark Souls is even harder, you have been warned!
The Dark Souls publishers have stated that there is no intention of
having additional downloadable content for the game as they believe the
game is set up in balanced complete state and is therefore unnecessary.
Metacritic.com states that Dark Souls is a dark fantasy RPG
designed to completely embrace the concepts of tension in dungeon
exploration, fear in encountering enemies, the joy of new discoveries,
and a high sense of achievement in progressing. The game is set in a
dark fantasy world filled with decadent atmosphere, with a heavy
emphasis on player freedom in discovering various tactics and strategies
to use in weapon based combat.
