I bought this set because I wanted a more natural tunnel complex than the very obviously carved tunnels that so many sets offer. I was not disappointed.
What I was disappointed in was that these tunnels are actually incompatible with most of the other sets. A common feature of dungeons is that part of the dungeon is natural and part of it is carved by humanoid hands. This set doesn’t feature a transition between the two, which means it's pretty much a standalone. Also, "landshark tunnels" doesn’t do the set justice, as it really limits the tunnels to one particular creature have burrowed them out when it could just as easily be a purple worm or an umber hulk.
The set is good for what it is, but it's not nearly as useful as the other sets in the e-Adventure Tiles line.
