PC. I don't own a PS3 or X360, and console warriors misusing the term "zeitgeist" to promote their platforms isn't convincing me to run out and buy either one. I'd rather get the best version of the game.
I don't know anything about this game (literally, I don't know if Bonfires are in this game, I don't know anything), and I intend to keep it this way.
Dark Souls II spoilers:
From Software replaced the bonfires with Vita-Chambers.
