Recently, I ran game where I didn't want all the key terrain out on the board since it'd give the players a sense of what was in store. So, drawing on my long familiarity with Too Fat Lardies games, I considered their use of Troop Blinds.
The Too Fat Lardies games use Troop Blinds to represent an unscouted force of unknown size & composition moving around on the board. So, I decided to create Terrain Blinds.
They are non-descript terrain placeholders that allowed me to show the players that something is in that area of the board, but that their figures can't tell what it was until they got closer. Otherwise, if I just left the "hidden" terrain piece off the board, the empty spaces would look funny & be a bit misleading to the players.
Here is the intial board set up. The terrain blinds are the flat green/brown patches circled.
Here is a close up of the blinds.
& once the players' figures got close enough to the blinds, here is what replaced the group of blinds in the right center of the initial picture.
I sure I'm not the 1st person to come up with the idea of hiding terrain from the players. I know I've seen fully laid out 3D dungeon crawls where the unexplored part of the dungeon is covered up to prevent the party from seeing what's ahead. But in all the wide & varied wargaming reading I've done, I've never seen the use of actual Terrain Blinds placeholders like this.
So please let me know if you've seen this kind of Terrain Blinds use before, & what you think of the idea.
