Origins of RoR

Some previous games related to RoR, and sources of inspiration for me:

• 1nsane by Codemasters: the same feeling of complete off-road freedom in a natural landscape. Also the cars are flexible objects, but not the wheels.
• Pontifex (also known as BCS) by ChronicLogic: similar physics engine, but for bridge building. RoR is a kind of "Pontifex on wheels", but lacks for the moment a truck editor.
• Hard Truck 2 by softlab-NSK: because of trucks of course! Interesting game logic based on economics that may be integrated in RoR one day...
