Games like Dying Light, where nightfall changes the rules

Games like Dying Light are easy to find if you only want parkour or only want zombies. These eight keep the part that matters: a city that becomes a different place after dark.

Games like Portal 2, where one idea carries the whole game

Games like Portal 2 all share one habit: teach a single impossible trick, then spend a campaign breaking it. From rewinding objects through time to Escher geometry that loops back on itself.

Games like Titanfall 2, for the pilot or for the Titan

Titanfall 2's campaign changed its own rules every mission. Games like Titanfall 2 that keep one part of it — the wall-running, the mech, or a campaign that never settles.

It Takes Two cannot be played alone, and that is the whole design. Games like It Takes Two that give each player a different job — including one that makes do with a single pair of hands.
