David Fair,
The pictures I showed was to show the terrain needed to be apply in the map. Even though it will be just a small difference, it still gives a small impact on what will be the tactics of the player. Whether the rocky type of terrain would be an advantage or disadvantage to him. And the purpose of the map was to show where was Little Round Top Located. And of course, that goes with the swamp too. I'm not saying that the fight took a major place in that map, I'm just showing the location of Little Round Top.
No offense, but in my point of view. Even if how many times you walked in a place that happen a century ago, you can never tell if the exact terrain of that place is still the same. Especially when you know that place is already populated with a lot of people. Well except if that is a historical landmark, or something. Which is in Gettysburg, not the whole Gettysburg or either the other places that took place in the war, is a historical landmark. We never know that some may happen to interfere that certain place that changed the outlook of it from a century ago.
Since this game is all about the war of Gettysburg in America, and since this is a RTS Game. While of course, controlling your units were to defend or attack (Most probably the game will be, since this is a 3 day war.). You may have the option to either follow what really happen in history, or follow your own tactics in mind. Even if the game will follow some parts of the Battle of Gettysburg, anything can still be change that depends on the player. But of course, I might go wrong since this game is still on developing. But on my idea, this is the most propable idea that they will make. Since the the group of DarthMod (creator of mods in TW) is in it.
That means, the whole garrison inside the building thing... Should be allowed, since this is a RTS Game. Sure, as I also have not heard any accounts that the houses around Gettysburg were occupied as fortified strong points. It still can provide as at least a small cover, in a war. Logically speaking, if you were a general in that situation. Will you at least, send a small unit inside a building to provide a greater defense? Well for me yes. Even if it's made out of wood, yet has a small benefit. But again, it always depends on the developers.
But thanks for the info though. Made me realize some important things to remember.
