I just came across this thanks to the power of targeted advertising. A company out of the UK called Room 17 games has created this Tenfold dungeon project:
This is a great concept for IA Maps. Especially take a look at the Miremarsh Swamp Glade. That is some beautiful artwork simulating outdoor terrain. Of course, it is mainly for fantasy dungeons, but you'll see they are offering sci fi doors, and some SciFi nurnies for their "Facility" tiles, which seems like something suited to a game like Space Hulk or something. I personally would love to play IA inside 3D rooms like these.
