Play Adventure Construction Set Online
You scribble dungeons in ASCII, drop joke loot like kitchen sinks, and wrestle with the janky editor until your weird little fantasy world somehow works.

Electronic Arts released Adventure Construction Set in 1985 for MS-DOS, a time when many players were still getting used to keyboard commands and monochrome monitors. It was a tool as much as a game, letting you build your own adventures from scratch or play through the included fantasy quests. In an era dominated by arcade ports and text adventures, it stood out for its sheer flexibility and DIY spirit.
You control a party of adventurers, moving them screen by screen through forests, towns, and dungeons you designed yourself. The goal is to complete quests, defeat monsters, and gather items, using simple mechanics like turn-based combat with swords or bows and managing your party's health and inventory. The pacing can be slow, especially when building your own worlds, and the difficulty varies wildly depending on what you or the pre-made scenarios throw at you. It feels like solving a puzzle you built with your own hands, full of surprises and occasional frustration when your creations don't behave as planned.
Each game uses different controls, most DOS games use the keyboard arrows. Some will use the mouse , "Alt" ,"Enter" and "Space bar".
