Dark Souls.
The messages are a neat addition, seeing other players ghosts is cool, and being able to summon others is really neat… but the constant fucking looming threat of a twink, cheater, hacker, or PvP expert invading you and killing you when you're trying to enjoy the PvE experience is a piece of SHIT.
Not to mention all the shit hackers can do to fuck with your world in Dark Souls 1.
It makes the best option to play without internet or as a hollow.
