Excalibur

Published in 1990 by Virgin Mastertronic and developed by Synergistic Software, Spirit of Excalibur (commonly catalogued simply as Excalibur on Mac shareware compilations) is an Arthurian role-playing game with heavy strategy and tactical-combat layers, set in 539 AD in the immediate aftermath of King Arthur's death at Camlann. Note: multiple Mac titles bear the Excalibur name; this entry treats the Synergistic strategy/RPG hybrid that fits the Combat/Strategy classification.

Setting and story

The player takes the role of Constantine III, Arthur's appointed successor, charged with holding sub-Roman Britain together against Saxon raiders, the rebellious sons of Mordred, and the supernatural plotting of Morgan le Fay. Across the campaign you recruit surviving knights of the Round Table, broker peace with petty kings, and chase the relics of Arthur's reign through a Britain whose Christian and pagan factions are pulling in opposite directions.

Gameplay

The game alternates between two modes. A strategic map of Britain is used to march armies, manage food and treasury, set tithes, and dispatch knights on diplomatic or quest missions. When two forces meet, or a knight enters a town or wilderness encounter, the engine drops to a top-down scene level for tactical combat or scripted adventure interactions, complete with conversations, swordplay and spellcasting. Magic is handled by Merlin and Nimue and consumes resources rather than mana points.

Engine and technical changes

The Macintosh build runs in 256 colours via 32-bit QuickDraw, requires a 68020 or later CPU, System 6.0.5+, 2 MB of RAM (4 MB recommended), and a hard drive. Synergistic ported its own multi-mode engine from the DOS original, keeping the same dual-scale (campaign map plus tactical view) presentation but redrawing the UI for the Mac's mouse-and-menu conventions.

Development and release

Synergistic Software, founded by Robert Clardy in 1978, had built a reputation on Apple II adventures (the Wilderness/Odyssey series) before signing with Virgin Mastertronic. Spirit of Excalibur shipped first on MS-DOS and Amiga in 1990 and was ported to Mac, Atari ST, Apple IIGS, and Commodore CDTV. A direct sequel, Vengeance of Excalibur, followed in 1991 and shifted the action to medieval Spain to chase the demon-lord Shadowmaster.

Reception and legacy

Reviews were mixed but generally positive: Dragon magazine awarded the DOS edition four of five stars; Amiga Action gave 70%, while Amiga Power and Zero placed it between 62 and 83 percent. Computer Gaming World called the visuals a "technical wonder" but criticised the manual. The dual strategic/tactical structure is often cited as a precursor to later Arthurian strategy games and helped cement Synergistic's late-career reputation before the studio was absorbed by Sierra in 1996.
