Avalanche press is releasing a new game shortly called Island of Death. It covers the invasion of Malta in WW2. The map is the entire island at 1km=1hex...which is the scale of OGRE/GEV!!
It looks GREAT an I can already see all sorts of potential scenarios like two ogres dueling to conquer the island. A force of Gev's and paratroopers trying to take the island from an OGRE. Give it a look!http://www.avalanchepress.com/gameIslandOfDeath.php
