A downloadable game

38th Century is a simple world simulation game made from scratch in 72h.

When a century is up, use the clues you noticed every decade to make the best investment for the century ahead (in one of defense, health care, industry, or science). If your prediction was correct, your population will be sheltered from the inevitable disasters that strike every 100 years.
