10 Cruel Tricks Video Games Played On RPG Players

For the most part, once you roll credits on an RPG, that's it - the game's over, and even if you start a new playthrough as a New Game+, the internal narrative continuity resets.

But Undertale has other ideas - it's designed to toy with the very idea of how we engage with video games. That is to say, it remembers your actions from previous playthroughs and, depending on what you did, punishes you for it.

Almost all players' first run through the game will be a Neutral Run, where neither the conditions for the Pacifist Run - killing nobody - or the Genocide Run - killing everyone - have been met.

You'll probably end up doing a Genocide Run at some point, whereby every boss guilt-trips you for killing them, the game's villages are largely empty as everyone flees from your reign of terror, and you get the worst ending possible.

Here's where it gets interesting, though: each subsequent playthrough will remember the massacre you committed during the Genocide Run and make constant note of it.

Even if you delete your save on Steam, the cloud will auto-restore it, ensuring the game never forgets what you've done - unless you're prepared to tinker with your computer's permission settings and stop Steam from reading the offending files.
