GMT has chosen to include reference cards for all units, which they have upgraded with each Expansion. Surprisingly, none for the terrain, which is not very much used in the first scenarios but that appears progressively in the different Expansions and C3i scenarios. Someone at BGG made a one-page summary for the terrain.
When I have introduced other users to the game, they felt a bit overwhelmed when they saw me laying on the table the board, the cards, one page for the terrain, two double pages for the units... and sometimes got lost in front of all the columns and rows!
I wanted something simpler, if possible with symbols (not all of my opponents speak english), and avoiding things like "See Note 1" or cross checking a row and a column to find out that the column does not apply to that unit ("--"). And including terrain (yes, I know terrain does not appear very often, but when it does sometimes I've forgotten the details...).
The file can be downloaded HERE (linked to original file on BoardGameGeek).
"Read More" if you would like to see how it looks like and how to create it by yourself!!
There are seven pages, but you only need the first two, pages 3 to 7 are the same as page 2 but with art from different armies. So choose from page 2 to 7 the army art you like the most, print together with page 1 on both sides of one page, cut upper and lower panels, glue them so that the UNIT panels are side-by-side, and fold them. Folded you'll have the TERRAIN on the back, open you'll have all UNITS at a glance.
The front half page tells you what the different symbols mean, though everything is quite intuitive (to me!). A beginner might get lost, but I made it for people who already know the game and just want to remind what a unit that was used some battles ago does. I've used the light chariot example in order to describe the symbols. The * refers to horse vs camel/elephant combat.
The file contains all units and terrain up to Exp#3, including Marshes, City Walls and Barbarian Chariots.
Enjoy!
