"Dunes Set - A graphic set based on the game Dunes"
It's actually simply called the "Dune" tileset. Please leave out the s there. The planet it's referring to is simply called Dune.
As it's based on the games "Dune 2000" and "Empreror: Battle for Dune" and to an extent also the first rts game ever: Dune II.
Otherwise good job on the list.
