Steam, Tracks, Trouble & Riddles (S.T.T.&R.) is a single player adventure mod, based on source engine (Orange Box) by Valve. It combines two types of game play: an adventure game with complex, 3D-interactive riddles in a fantastic environment and a simulator for track based vehicles.
New props for the world of S.T.T.& R.
I think the one on the right looks great. But the one on the left just seems a bit plain :/
I have to agree with Raider7 the one on the left looks slightly plain. I would believe that is because of the the texture not including enough ware for a post-warfare state.
