A number of hidden game mechanics have been dragged into the light after a Twitter question from a designer in Australia went thermonuclear over the weekend.

On Friday, Opaque Space design lead Jennifer Scheurle asked Twitter to tell her about "some brilliant mechanics in games that are hidden from the player to get across a certain feeling".

An example she gave was from Assassin's Creed and Doom, where your last bit of health is actually worth more hitpoints than it should be in order to encourage a feeling of just barely surviving.

A huge number of developers – both famous and not so famous – then chimed in, and the thread made it onto Reddit and eventually media sites, where still more developers chipped in in the comments.

Some of my favourites are below, but the original thread, or this much-abridged Reddit summary are worth reading in full.

Scheurle, who emigrated from Germany to Melbourne, is currently working on narrative-driven space exploration VR title Earthlight at Opaque Space, and "modempunk" stealth space-trading game Objects in Space at Flat Earth Games.

She's also in New Zealand this week to speak at the New Zealand Game Developers Conference in Auckland (something answers from her epic Twitter thread will feature in!).
