It's gopod to hear that you like the building textures, since that is where most of my time has gone over the last month of development. Texturing the buildings with tiling materials has been a challenge. I plan to give the building textures another pass eventually, but it's way down the road. Ground textures will get attention in a few releases. Right now I just have one grass and one concrete texture over the whole map, with no ground decals. This allows me to move things around easily, but it doesn't look great. Once the building layout gets locked in a little more, I'll get the ground textures refined. After that I'll add parking lot striping and ground decals. I actually had to repaint all the ground texture over the last two days, because the game trashed my terraintexture.pak, leaving all the ground white. It's a bit of a rush job, but it isn't an area I am overly concerned with right now. I'd like to add some benches and street-lamps too, but right now they just impede gameplay. If they aren't destructible, they just become mech obstacles.
The version number on each release should give you a rough estimate of where I am in my development road-map. I still have a long way to go. For the next update, I have mostly optimization planned. Once I get done with that stuff, and test this layout a bit more, I'll start on the terrain textures. You can probably expect to see that stuff in a 0.5 release. Like I did with the current details that have been added, I'll work on that from the center of the city outward.
