The flash game for Top Gear has finally been unleashed onto the interwebbamajig.
Did all the graphics, but I found filter forge 2 invaluable for making the texture sets for the landscape. Very nice program there !
You can play the game yourself at Top Gear Continental Rally
May update; there was also another version made for Peugeot with three different terrains.
