From High Voltage Software, the makes of Cortizone, Brainchild was an unreleased/unfinished (?) adventure game with ideas crowd-sourced from the readers of Syntax magazine (as well as Red Herring & Adventure Probe). A bare-bones adventure was available for contributors to look at.
From the original introduction: "Basically, the game will be the adventure equivalent of a Chinese whisper, starting off with just a few rooms to which are added the best ideas sent in by the readers of SynTax."
