The PlayStation 4's design — not the actual shape of the console, but the system's emphasis on social gaming experiences — was inspired by Demon's Souls and Dark Souls.
No, the PS4 isn't meant to crush your spirits, but rather, the games' abilities to make you feel connected, but not really connected at the same time was a inspiration for the PS4 design team.
"Lots of things these games – Demon’s Souls and Dark Souls – did, like leaving the message to other people asynchronously so you feel connected but not really connected at the same time, all of these things inspired us when we were designing the system features for PS4," explained Shuhei Yoshida, Sony Computer Entertainment Worldwide President, on the latest PlayStation Blog podcast.
"The sharing features – I enjoy so much watching people playing Dark Souls on YouTube. These games still have special place in my memory."
The PlayStation 4 undoubtedly has a heavy emphasis on the social aspect of gaming. Aside from its Pinterest-like "What's New" menu, which highlights your friends' latest game updates and achievements, the PS4 also includes built-in streaming functionality and Facebook integration. Sony also has plans to add a feature that will let players remotely take control of a friend's game via the internet.
I suppose if there are two games for the "gamer's console" to take inspiration from, they should be these two.
