Thanks Ferrous for starting this thread. Just discovered it today.
I normally follow the "USA Pics" thread, but I think this is going to be my favourite from now on. It highlights the landscape, textures and assets rather than the trains (just my preference) and it has scenes from everywhere, not just from the US of A.
Those shots by Spikerod and Mezzoprezzo are especially convincing, I just want to jump through the screen and BE in those worlds!
I'm also looking at them and thinking that the officially maligned 'billboard' style trees are still way better than Speedtrees, at least for screenshots. Probably get hung for saying that again...
