During this period, the idea that indie games could provide experimental gameplay concepts or demonstrate niche arthouse appeal had been established. Many games from the bedroom coders of the United Kingdom, such as "Manic Miner" (1983), incorporated the quirkiness of British humour and made them highly experimental games. Other games like "Alien Garden" (1982) showed highly-experimental gameplay. Infocom itself advertised its text-based interactive fiction games by eschewing their lack of graphics in lieu of the players' imagination, at a time that graphics-heavy action games were commonplace.
