The addition of flying units and anti-air units add a new dynamic, as now you must fight to dominate the skies as well as the land and sea. In addition to the re-skin, this game boasts numerous other cool features that help make it a unique and standalone title separate from its AoE II predecessor.
Whilst in AoE II all units were identical in appearance, in this game each faction has undergone a complete re-skin, meaning that an Empire trooper is a storm trooper, a Trade Federation trooper is a battle droid, and so on. Like AoE II, each of the factions (eight in total – the Trade Federation, the Republic, the Confederacy, the Gungans, the Rebel Alliance, the Empire, Naboo and the Wookies) largely have the same units and buildings available, with some variety due to faction-specific abilities.
Dropped straight into the same engine as the much-adored Age of Empires II, Star Wars: Galactic Battlegrounds is a Real-Time Strategy game set, funnily enough, in the Star Wars universe (from episodes I, II, IV, V and VI).
I gawped slightly as I learned that this game (now undoubtedly a classic) first came out in 2001.
