Wilderness paths is probably one of the most commonly used tiles you'll need. Most outdoor encounters take place on these kinds of paths. Like the Deciduous Wilderness tiles, they're not square and therefore not easily interchangeable, but that's not a huge problem for me. SkeletonKey Games brings clarity to the battlemap spaces, and I prioritize that over realistic-looking 3D terrain. Easy to print, easy to use, this worked fine for my purposes.
