Lots of bricks, stones, pavers, etc. in the LPC style. In general, anything that I thought looked just as good pasted over the top of all the other terrains. Comes in lots of colors, probably too many. Includes Tiled terrains. 

Update 2021-01-01 (Version 6): re-arranged tileset to include most bricks in all colors. Added full terrain sets for arc/fan-patterned stones, and square bricks; added curbs; extended some brick sets with rounded corners to allow smoother diagonals; added more simple bricks to bottom. License changes to CC-BY-4.0 due to inclusion of tiles from n2liquid. This set is not backwards-compatible with the previous version (v5), so those assets remain available.
