In the NES version only credits are required to buy craft, whereas the original versions require the player to spend money, minerals, fuel and energy (though this varies depending on the difficulty level). Finally, the use of the docking bays is more complex in the home computer versions, which also feature an image of the face of the enemy that grows clearer the closer the player is to completing the game. Reception The main theme composed by Jeroen Tel is recognized as one of the best SID musical compositions ever made, reaching the 52nd spot among almost 30,000 entries in the High Voltage SID Collection. Computer Gaming World in 1991 described the computer version of the game as "easy to learn and a delight to play ... Overlord conquered this reviewer's taste". In a 1992 survey of science fiction games the magazine gave the title one-plus stars of five, stating that the computer opponent did not adapt to faster clock speeds and became unplayable. Flyingomelette gave the NES version a rating of 2/10 stars, saying, "It isn't often that a game comes along that challenges my notions of just how bad a game can really be. (...) What appeared to be a very promising simulation and strategy game for the NES, ends up being a complete disaster, due to the many elements that all work against you, all at once, much too quickly".
