Some assets I modelled and textured for the game "Detour" by Sandswept Studios.
Each tile/prop is around 100-1000 tris, using a mix of 64x64, 128x128 and 256x256 textures.
The white areas on each model is an alpha layer that is used to define the "team colors", so the buildings, vehicles, weapons and roads can easily be distinguishable between different players in game.
Here is a trailer for the game:
