Open-World RPGs: 7 Games Where Killing NPCs Ruins Runs [Guide]

Open-world RPGs punish impulsive combat decisions by locking critical quest lines, permanently eliminating merchants, and breaking storyline progression when players execute essential non-playable characters across games like Elden Ring, Fallout New Vegas, and The Elder Scrolls III Morrowind. According to verified reports from Game Rant, player freedom in sandbox role-playing games frequently collides with irreversible narrative friction. In titles such as Fallout: New Vegas, assassinating faction leaders immediately alters karma alignments, triggers hostile territory lockdowns, and forfeits unique companion rewards. Similarly, FromSoftware's Elden Ring forces players to seek out Celestial Dew at the Church of Vows to atone for sins if vital quest givers or shopkeepers are mistakenly slain. Even retro classics like Morrowind famously broke main quest threads with the infamous 'thread of prophecy is severed' warning.
