For me the additional detail of the tanks, etc. is lost - I don't normally zoom in tight enough where additional detail there would make a difference.
What I would like to see are roads that curve naturally and smaller action tiles. Those changes would have the most impact to the way I play, I think.
And also, while I am at it, I would like to see true multiplayer games, i.e. 4 on 5, etc. I have lost track of that request over the years - what's the latest?
