A free transportation simulator game
Simutrans is a cross-platform simulation game where players try to successfully manage transportation systems between places by land, air, and water for passengers, mail, and goods. Planes, ships, trains, trams, trucks, buses, or monorails are at your disposal, but factories operate based on contracts and passengers can only travel to their set destinations.
World of Tanks II: New Realy cool clone of BATTLE CITY from Dendy. There is a team play on one keyboard at the same time, not bad graphics, sound & music... I'm very sad I had found it and added support of WindowsXP only after 4 years it was written.
