Although it may sound really stupid initially (and to some, I guess, permanently!), I was thinking it would be great (stratigically) to have the map be able to be tilted a bit so you get a good sense of the elevation.
Granted, a map is a map... and should be flat, and I totally respect that. If we are simulating a paper map, then, ya, for sure... it should be just as a real map.
Also, yes, the elevation markings should be sufficient to indicate the elevation... to those who are comfortable reading real map elevation markings.
So, this suggestion is just that... a 'throw this idea in the 'when we have tons of time and nothing better to do' pile' type of thing... more for people to really plan out their stratagies, as opposed to a simulation of a map. I agree, it is not something that real soldiers would have, and on that basis alone, it could be rightfully pooh-pooh'd, and that would be that... no arguement.
As with all my suggestions, I'd want it to be OPTIONAL... as not everyone wants that obviously, and I'm not trying to push it on anyone.
Starting a conversation... Enjoy shooting it down.
