I think it was Res Gestae that pioneered the tilted map.

Those stratmap models do look fantastic. Would they show up that way in the distance on the battlefield too? One thing in EB I love is that I seem to be fighting near cities a lot more often, and it's great seeing a city or town on the plain below; it'd be even better if the models were as stunning as Prometheus'.

Slightly related, are those weird flat coastal squares fixed in 1.5? Where there should be a port there'd be a flat area, for instance.
