AMOS

AMOS (later AMOS Professional) was a game creation language for the Amiga created by François Lionet and published by Europress in 1990. It combined BASIC syntax with powerful commands for sprites, bobs, screens, sound, and animation—everything needed to make Amiga games without learning assembly. AMOS proved that accessible tools could produce commercial-quality games.

Where Mandarin came from

The publisher line above — “Europress/Mandarin” — has a history worth knowing, because Mandarin did not start as a tools imprint.

Mandarin was created in early 1988 by Europress International specifically to publish Level 9, Britain’s leading text-adventure house, which had just severed relations with Rainbird over repeated delays to Time and Magik. ACE reported the signing that March; the label was run by Chris Payne, previously of MicroPower.

Two years later the same imprint published AMOS. A label founded to distribute one adventure studio’s back catalogue became the home of the Amiga’s most widely used game-creation language — which is a fair illustration of how small and how mobile the British software business still was at the turn of the decade.
