Souls-like

What about Souls-like?
Much like Roguelike starting with a game called Rogue, Souls-like started with a game (series) called Demon's Souls. Released in 2009, Demon's Souls was followed by the Dark Souls series. The series of action role-playing games (action RPGs) is, much like its rogue-counterparts, known for its high level of difficulty.
