FSO's take advantage of some very nicely built maps (Kudu's to Dux & his crew)
Often you can get maps for special events which are based on real places and those will have place names, etc. Like you I like it, it all adds to immersion.
You won't see that in the main because those maps are designed for a totally different setup. They have to be designed to be balanced so that no one of the 3 sides has a starting advantage, or disadvantage.
So they tend not to use real life terrain, with real place names. Making it from scratch, so that the fighting and gameplay flows smoothly.
If AH maps based on real places is what your into, I'd strongly suggest checking out the AH events site.
Snapshots, FSO, or full blown scenarios are often designed around top quality player designed maps.
