Game Over in Machinimation Trivia (Windows)
Relation To SidrialThis game is actually a somewhat-modified version of Fountainhead's original Machinima project, "Sidrial." Not long after the concept of "machinima" (creating animated films using real-time game engines instead of traditional animation) started to take off, Sidrial was to be the first completely original animated feature to be created from scratch on the Quake III Arena engine. While the feature-length film idea never got off the ground, the assets were compiled into a total conversion mod for Quake III which can still be downloaded from the Internet Archive.
It seems Game Over in Machinimation is built on top of the assets for Sidrial, with some characters replaced and a few extra features added. Even the ridiculously elaborate Sidrial HUD is still present!
