A long time ago, I started a thread and a uservoice for what I call "fog cards".
"Fog cards" would be cards that change the fog settings in a part of the map (I suppose they could work like Reconaissance - a target territory. Surveillance - a target bonus, or Spy cards - a target player).
I wrote about the idea here, originally, with some discussion:https://www.warzone.com/Forum/107556-new-concept-fog-cards
There was a uservoice, here:https://warlight.uservoice.com/forums/77051-warzone-features/suggestions/12592782-fog-cards
And a later thread, with less useful discussion, except for the concept of "bunkers" and discussing the interaction of various card types, here:http://188.8.131.52/Forum/138776-new-idea-fog-cards-make-uservoice
For the purposes of understanding all this, the first link has the most info - I'm only including the others to be thorough.
Now that that members are able to work on and implement mods, is this concept feasible? Can it be done?
I think a lot of neat strategies, as well as interesting maps and scenarios, could be accomplished with Fog Cards.
