One of my favorite Amiga games in the 90's was Another World.
raw is a re-implementation of the engine used in the game Another World. This game, released under the name Out Of This World in non-European countries, was written by Eric Chahi at the beginning of the '90s. More information can be found here : http://www.mobygames.com/game/sheet/p,2/gameId,564/.
