Maps based on well-known game universes and real-world geography.

I suggest posting them here; I think many will find them interesting.

And I propose visiting http://all4heroes.net/ – there are definitely such maps available there.
Also, a section for all maps for Heroes 3 (AB, RoE, and SoD) is located here: /topic/140/ – if you look closely, you can easily find what you need.
Apart from off-topic discussions, the thread hasn't provided anything of interest in the past two weeks – the topic is closed.
