The Adventures of Robin Hood is an adventure game created by Millennium Interactive and published for Amiga, Atari ST and MS-DOS in 1991.
The game, based on the legend of Robin Hood, was designed by Steve Grand and Ian Saunter. Despite being considered an adventure, don't expect a point-and-click, this is more like a "god game". You can't control the hero directly, the gameplay and the visual interface are similar to Populous. You can see a portion of the world from a top-down isometric view, and you can interact using the icons on the left.
The Adventures of Robin Hood is a pretty unique game, with entirely non-linear gameplay, plenty of small puzzles to solve, quests, characters and other things to do. Your main goal is to regain the castle from the Sheriff, but how to do this, it's up to you. You can also ignore the final goal and just enjoy the game. Some people have compared this game to GTA, or some open-world RPGs, or even The Sims. What is important is this game is fun and really enjoyable.
