Alien Isolation

[Cyan]

I found it interesting that you can skip almost all levels and the game still works.

that's one of the reasons that make speedruns quite fascinating, specially the fact of how people discover such tricks, it's amazing stuff if you think about it, how they end up finding secret exploits no one predicted (nor they thought they existed), not even the game programmers. Sometimes you see certain exploits and you go: "man, who and how found out about this?".

this game would be imho one of the best showcases of Raytracing, and having everything raytraced with so many lights and shadows, or trying to escape the alien, seeing the alien's shadow in certain places where traditional rasterisation can't show him would make for the ideal atmosphere.
