The 3x3 block now looks like mini-hills and is great for placing around actual hill terrain to blend it into open terrain. I just wish there was a 2x2 equivalent.
The 2x2 block with the stone in it is nice too for the same reason. It's just too bad that the stone block wasn't 1x1 so it was easier to place.
Now we just need some 2x2 and 3x3 open terrain tile sets with a couple of trees / cattails / sand / snow to blend with the other terrains
