There's a couple of things I really like about them, that gives advantages over others. They're tiles, so not stuck in a book. They're all the same footprint, so you don't have tiles falling and shuffling up all over the place, in a box, and so it's less fiddly to just place them on a table, you can have them stacked in order you are going to lay them down, means you're not breaking the flow of a game as much. This means they're more easily transported than my box endless encounters. ALL of the tiles are reversible, with the flip side being a different version of the SAME room space, so you can actually place them prior to the group entering a dungeon, but not reveal important clues, bar the layout. Also they are printed so you flip the tile and don't have to rotate it, I know that's a minor thing, but shows thought into it. Maybe It's and OCD, but it's annoying when you flip other dungeon tiles to use a reversible version, but have to then then it 180 too. I wonder if they can be numbered somehow without interrupting the art? Then encounters can be planned more easily using them?
