OpenTTD:
OpenTTD (Open Transport Tycoon Deluxe) is a computer game where the player is in control of a transport company. Each player competes against rival companies to make as much profit as possible by transporting passengers and various goods by road, rail, sea or by air. If playing solo, one plays against the computer. OpenTTD is a free clone of Transport Tycoon Deluxe.
Some constructions:
Simple 4-way junction
Simple Turnround for a 4 track line
Three big stations
A very crappy station with 22 platforms (20 in use)
Very nice train income ;-)
A stupid traffic jam :(
