When it comes to licensing and promotion, George Lucas has never been shy. After completing Star Wars: A New Hope in 1977, the writer/director spent considerable time and effort fine-tuning the subsequent marketing assault. Toys, books, lunchboxes and an R2-D2 spatula all appeared, some of them taking a side-step away from the main characters of the movies, creating their own stories, heroes and villains; some of them taking those familiar characters and putting them in unfamiliar settings.

Now, almost 40 years since the release of A New Hope, we finally have a cinematic Star Wars spin-off in Rogue One. Video games have long retained this tradition; the Star Wars universe contains such scope for extracurricular adventures, that it would have seemed churlish not to explore them. And explore them developers have, bolting on the characters from the sci-fi epic to whatever type of game they could label, package, promote and sell, usually creating new characters and worlds in the process. Here's some of the best - and worst - of Star Wars spin-off games from history.

Star Wars: Droids (1988) shout>Platforms: Amstrad, ZX Spectrum, Commodore 64 Icon-driven madness in Star Wars: Droids on the ZX Spectrum. Star Wars: Droids has the distinguished honour of being a spin-off of a spin-off. Aired on Saturday mornings between 1985 and 1986 (plus latter repeats in the UK), the cartoon occupied that void left by the temporary end of the series with Return Of The Jedi in 1983, and The Phantom Menace some 16 years later. The cartoon itself was average; the videogame based on it, licensed by UK budget powerhouse Mastertronic, was lamentable. As the name suggests, the game stars that irascible duo, C3P0 and R2D2 in an adventure set just before A New Hope. Having been kidnapped by an unpleasant gang, the pair must escape through a series of tunnels, avoiding traps and enemy robots. There are two major issues with Star Wars: Droids. First of all, the formerly peace-loving 3P0 is now a destruction-wielding bastard, flinging deadly bombs at enemies, while the designers saw fit to utilize a bizarre icon-driven control method that renders the game virtually unplayable. Even for the low price of £2.99, it's hard to imagine many Spectrum, Amstrad or Commodore 64 owners being particularly chuffed with this back in 1988, despite the famous characters.

Rebel Assault (1993) Platforms: PC, Mega CD Rebel Assault looked exciting but sadly wasn't quite as action-packed as it promised. With different characters thrust into roles that echoed their movie counterparts, Rebel Assault skipped vaguely alongside the plot of A New Hope, while introducing the occasional new planet to mix things up. Starting off with a training mission on the familiar scene of Tatooine, the player takes control of Rookie One, A Luke Skywalker-esque ingénue learning the ropes and yearning to join the rebellion. Soon Rookie One is jetting into outer space, taking on Star Destroyers, TIE Fighters and, ultimately, the Death Star itself. Time has not been kind to Rebel Assault. A product of an era where CD-ROMs were beginning to find a foothold as a medium, its limited FMV on-rails blasting action seems laughably limited by today's standards. Iconic segments such as assaulting AT-ATs on Hoth are relegated to boring fly-bys, punctuated by the odd bit of targeting and shooting against a leg or head. Yet viewed with an early-90s perspective, Rebel Assault was a dramatic shift from the Nintendo platform jumping games that the series had until then specialised in. Now players could hop into an X-Wing and take on the Empire, accompanied crucially, by the famous John Williams score. As for Rookie One? He probably met an untimely death back in Beggar's Canyon, trying to control his unwieldy T-16 Skyhopper. See also: Rebel Assault 2: The Hidden Empire (PC, PlayStation)

Dark Forces (1995) Platforms: PC, PlayStation Blasting Stormtroopers in Dark Forces. The original Dark Forces, inspired by the success of Doom, introduced fans to Kyle Katarn, former Imperial officer turned mercenary, hired by the rebels in a story set just prior to A New Hope. The game's obligatory pre-game crawl reveals some interesting information; described as a 'rogue', Katarn's first mission is to infiltrate an Imperial base and pilfer - you guessed it - the Empire's Death Star plans. That done, Katarn is given more tasks by the rebels, chiefly investigating and eliminating the Empire's Dark Trooper program, cybernetic super soldiers laden with superior weapons and armour. Like most of these spin-offs, Dark Forces included familiar locations from the movies, although technology of the time limited the appearance of the iconic vehicles. There was Stormtrooper blasting abound, however, and huge fun to be had in wandering the atmospheric levels. The engine itself was hugely improved over Doom; Katarn could jump, look up and down and a then-complex map of rooms-over-rooms was employed. Dark Forces' sequel, Jedi Knight, saw Katarn fully inducted into the rebellion and as the name suggests, becoming a Jedi himself. But for almost 21 years, he was the man who stole the Death Star plans. See also: Dark Forces 2: Jedi Knight (1997)

Star Wars Monopoly (1997) Platforms: PC Published under licence by Hasbro, Star Wars Monopoly, as the name clearly suggested, was the classic trading game updated with Star Wars characters and locations. The board game (unlike its recent iteration) followed the original's template closely; gone are Old Kent Road, Vine Street and Mayfair; in come Lars Homestead, Dagobah Swamp and Imperial Palace, Coruscant. Houses and hotels are replaced with colonies and starports, and there are new utilities, too, such as the moisture farm, plus chance cards are replaced by bounty tasks. The videogame version was released in 1997 by Hasbro's Interactive label, and is good fun for any budding entrepreneur with even a passing interest in Star Wars. The player pieces are famous characters from the movies, and they dash nimbly across the board, the determining dice roll primed by laser fire from the Millennium Falcon or another space vehicle. Clips from the movie punctuate the action, as do occasional TIE Fighter/X-Wing battles, and overall it's a decent stab at an interactive board game, albeit one that's likely to go on for a long, long time and end up in a family argument. Sorry about the mess. See also: Star Wars Chess (1993)
