That sounds pretty sweet. I might see if Demon's Souls is available on Steam.
I'm really tempted to go through the first Dark Souls and start a completely new character, now that Dark Souls II has given me a better understanding of the game and its mechanics, but the only thing that bothers me is the lack of fast travel. Yes, this is a total cop out on my behalf and I can imagine people rolling their eyes as I say this, but man I loved the fast travel feature of Dark Souls II. Made things a lot more convenient.
I might see what MODs are available for both games.
