If you love the theme but are on the fence and feel like your falling on the side of going for it? I'd say jump in and grab it
Played three games so far, died horribly every time
They come in plastic grids and must be cut out with an exacto knife or model snippers and then assembled
Both are really cheap, the cutters can be found at any craft store
However, the online videos are very good at showing the ease of actually playing
My advice, if you have the means, is to grab either City Of The Ancients or Swamps Of Death
