I've been awake now for 5 hours and have finally decided on a game idea which I think I can manage in the time frame.

The Story is basically like the film Snowpiercer, some humans have moved onto a train to escape some crazy impending doom which requires them to remain in motion. The train needs to keep moving along a track to maintain power or warmth. To facilitate this, they developed an A.I. to maintain the tracks, which span the world. During development, mistakes were made, and a bad A.I. was developed as well. You control the 'good' A.I.

Hopefully, this track system with trains will be finished today...
