Demon's Souls started the series and deserves a remaster because it's the reason that the series made it thus far, please Hidetaka Miyazaki please, everyone wants it.

Dark Souls this is considered the best game of the souls series by a lot of people, if this gets remastered I'm sure both party's would be happy. Us as the consumer  who gets to experience this awesome game again with better graphics etc., and you as I'm sure people would pay for the remastered versions of both these great games.
