Starting from the ground up with individual pixels and attribute statistics, Adventure Construction Set allows Apple II users to create their own 2-D RPG/quest-style game worlds, populate them with characters, and then allow other players to explore these new realms. Though a few "stock" graphics are included, ACS gives the Lord British and Scott Adams wanna-bes the means to draw their own background tiles for terrain, buildings, obstacles and items, not to mention characters and monsters that will inhabit those spaces. Attributes are then generated for each of these things -- how fast can characters travel on grass as opposed to desert? Can mountains be climbed over, or will they bring any adventurers to a complete halt? Just how powerful is an Orc, anyway? And is there a weapon hidden anywhere in the world that will fell any enemy with a single blow -- and, come to think of it, is there an enemy out there who can do that to the player?
Some minimal "dialogue" can be attached to non-player characters, and the "world" itself is drawn in a utility very much like a paint program. The end result is a nicely-put-together (assuming the game creator has done his homework) God's-eye-view game, not unlike the early Ultima titles. It's a good idea for those trying to make games with ACS to have a good understanding of the Apple II's color palette and how its colors can sometimes cause undesirable interactions with one another. ACS is a brilliant piece of software that provides budding dungeon masters with the tools they need to conjure up their own grand quests, though playing the resulting game was never as engrossing as making it. The Adventure Construction Set concept has been carried forward to such modern titles as RPG Maker for the PlayStation.
