So I've been following this game called Spin Tires by Oovee studios. Their kickstarter funded so they will be making a full game. I downloaded the demo and fooled around in it, seems pretty detailed and fun. You can lock your diffs, change from 4x4 to 4x2, change gears, in the full game you will be able to use winches and stuff they said. Anyone played this yet? I think its going to be good.
