FFG, here's a tile product that will sell - Death Star Tile Kit.
On one side is the Death Star surface and you can lay the tiles in a 3x3 pattern on which to play or if you buy multiple kits, lay down as many as you want, like for a 200 point battle.
Six pre-painted plastic Turbolaser Towers come with to use on the surface or in the trench.
On the reverse side of each tile is a piece of the Death Star trench. Lay these tiles end to end for a great trench run.
Scenario rules would be included.
Now THAT tile kit would sell!
