I am not sorry that I purchased them - given the price, but these could have been so much better (like all of the e-Adventure sets). I could pretty much put the same knocks unto most of the e-Adventure tiles.
1) They are not square. This is a very bit hit against these tiles. Because they are not square you cannot easily rotate them to change a setup. I cannot stress how important this knock is against the e-Adventure tiles. These tiles are 6x9 - so you can do 3x2 tiles rotated, but this makes mixing and matching a nightmare.
2) No layering. PDFs have a wonderful layering capability that give easy access to a larger number of tiles simply by turning on and off different layers. Sure, they accomplish the same thing by including a decent number of tiles, but it is not like this set contains that many tiles.
For this specific set.
A) There are some nice tiles here. They transition well from other green fielded sets of the e-Adventure set.
